QR Code, a two-dimensional bar code storing addresses and URLs, is a widely used technology in Japan and elsewhere that can be scanned with camera phones equipped with the appropriate reader.
It's likely to gain ground quickly in the U.S. now that Google has sent out a QR code to 100,000 of the most popular companies in its Local Business Center. When those companies display the QR code, customers can use code-scanning applications on their iPhones and other devices to retrieve the firm's individual Google listing.
The only problem is, many of those QR code-reading apps for the iPhone just don't do a good job. That prompted me to sift through more than a dozen QR code readers to find some of the best. I came up with four.
QR Code it up
NeoReader NeoReader is one of the most useful apps in this roundup. The program is simple, it's intuitive, and it does a relatively good job of reading QR codes.
NeoReader is an extremely simple app. When it's open, you need only to point your iPhone's camera at the QR Code, click the scan option, and you're all set. Within a few seconds, the app delivers the unique content directly to your iPhone. It works with QR (obviously), as well as Data Matrix, and Aztec bar codes. To ensure the app is working properly, you can even go to NeoReader's home page and scan the QR Code examples to see if it's returning the right results. But beware that the application works best on iPhones running OS 3.0 or higher. NeoReader is free, so it's worth trying out.

Overall, Optiscan is a really nice QR Code reader. The application is able to capture QR codes on monitors, paper, and other places where you might find the code. Upon scanning a QR code within the app, you can view the company's QR code information. You can also save that data for later, so you don't have to come back to the QR code every time you want to view it. Even better, Optiscan allows you to share QR codes with others. It's a full-featured app that should satisfy most users. It costs $1.99.

(Credit: Optiscan)Would you like to let AT&T know when your iPhone has dropped a call? Well, now there is an app for that.
AT&T on Monday released a new application called "Mark the Spot," which lets iPhone users submit complaints about dropped calls, poor service coverage, and less-than-perfect voice quality.
The application is free and available in the iTunes App Store. It uses GPS technology in the iPhone 3G and the iPhone 3GS to pin point where the user is when experiencing the problems. For first generation iPhones, it uses cell tower-triangulation to get a fix on problem areas.
Once the application is launched, users have several complaint options. They will see a screen that has buttons that let them report a dropped call, poor voice quality, or poor service coverage.
AT&T spokesman Mark Siegel said AT&T plans to use the data collected to identify trends and prioritize the company's network investments.
"We think this is a great way to get customer feedback to improve our network," Siegel said. "We are always looking for ways to make it easy for customers to share their experiences. And this app lets customers report issues. It logs the time and location and automatically forwards the information to our network planning team."
iPhone owners have been complaining about AT&T's network since the Apple iPhone went on sale in the summer of 2007. Complaints mounted after the 3G version of the phone was released a year later in 2008. And as more iPhone users come onto the network, more people, particularly in densely populated urban areas, such as New York City and San Francisco, have experienced problems with dropped calls and congested data networks.
AT&T executives have not admitted that AT&T has a problem with its network. But executives, such as AT&T Chief Technology Officer John Donovan, have said that the company has seen a surge in data traffic attributed to iPhone users, who typically consume more wireless bandwidth than other AT&T wireless customers.
AT&T has been upgrading its network to keep up with demand. But problems persist. And AT&T's network recently got a poor ranking in terms of customer satisfaction in a Consumer Reports survey.
Verizon Wireless, AT&T's chief rival, has taken advantage of AT&T's struggles with a series of advertisements that point out AT&T's lack of 3G network coverage in certain parts of the country. Verizon is running advertisements that mock the Apple "There's an app for that," catch phrase with one that says, "There's a map for that."
AT&T fired back with a lawsuit and an advertisements of its own featuring actor Luke Wilson, who points out AT&T's strengths while taking a few shots at Verizon Wireless.
AT&T recently dropped its lawsuit against Verizon. And Verizon, which had been suing AT&T over claims that it has the fastest 3G wireless network, also dropped its lawsuit against AT&T.
Siegel said that the new "Mark the Spot" application was not prompted by the bad publicity around its network issues nor was it prompted by the current ad wars going on between AT&T and Verizon. Instead, he said that the application was simply a part of AT&T's ongoing commitment to listening to customers.
"We are always looking at ways to get customer feedback in as timely a manner as possible," he said. "That's why we pay attention to Twitter, Facebook and blog. One of the great values of these social networking tools is that it's a great way to get instant feedback. And it helps us identify problems."
The "Mark the Spot" application can be downloaded onto all iPhones running version 3.0 or later of Apple's operating system or it can be access using iTunes and synchronized to the iPhone via a PC or Mac.
Siegel said that AT&T is testing the "Mark the Spot" app for other devices. And he said AT&T hopes to offer applications on other smartphones in the future. No date has been announced yet. And Siegel didn't specify which devices might get the new application, but considering that AT&T sells a lot of Research in Motion's BlackBerry devices, it's likely it will create an application for that device. The app could be offered through AT&T's own application storefront or through RIM's BlackBerry App World.
Now that Black Friday and Cyber Monday are just a memory, the holiday season is in full swing. For those of us who like to be organized when we hit the stores, creating a shopping list is really the best way to go.
Unfortunately, though, there aren't many services that do a great job at creating those shopping lists. Too often, they provide very simple functionality. Realizing that, I've compiled a handful of services that do perform well for anyone looking to get organized this holiday-shopping season. In this list, you'll find a few sites and a few iPhone apps to check out.
Let's get started.
Get your shopping on
Amazon Shopping List Not to be confused with the company's Wishlist, Amazon's shopping list helps you keep track of all the products you want to buy.
Overall, Amazon's Shopping List is useful. It's not the best service in this roundup, but it if you're looking for simple, one-click experience, Amazon's tool provides it. That said, I should note that you can't simply add any product on Amazon to the list. Unfortunately, I could only find items that could be added in the grocery, beauty, gourmet food, and health and personal care pages. Even then, not all the products listed in those categories were capable of being added to the shopping list. It was a little disappointing. But if you're a heavy Amazon customer who shops in those categories, try it out. If not, there are some better services out there.
My Amazon shopping list needs more products!

When you start using Boxedup, you'll need to download a Boxedup button that's added to your browser (I was using Firefox, which it works well with). From there, simply go out to any online retail site and click on the Boxedup button when you want to add the item to your shopping list. Upon doing so, it's added to your Boxedup list for later viewing. You can also add items to your profile right from the Boxedup page, but to be quite honest, that's not how the service was designed and that functionality is a little suspect. Regardless, having the option to add content to your list from just about anywhere on the Web is fantastic. Boxedup works quite well. Check it out.

Another iPhone worm has been spotted in the wild.
Unlike the previous exploitation, which merely changed a jailbroken iPhone's wallpaper to a picture of Rick Astley of "Rickrolling" fame, this new threat allows hackers to steal sensitive information.
According to security firm Sophos, which wrote about the exploitation after a Dutch ISP spotted it late last week, the worm attacks jailbroken iPhone and iPod Touch devices only.
The worm "uses command-and-control, like a traditional PC botnet," Sophos wrote in a blog post on Saturday to warn users about the exploit. "It configures two startup scripts, one to execute the worm on boot-up, and the other to create a connection to a Lithuanian server to upload stolen data and cede control to the bot master."
Jailbreaking, which has been around for about two years, is a hack that enables iPhone and iPod Touch users to download applications unavailable through Apple's App Store.
Sophos wrote that the worm attacks users on several ISPs, including UPC in the Netherlands, Optus in Australia, and T-Mobile in several countries worldwide. Worse, the worm spreads faster on a Wi-Fi connection than a 3G connection. Users with affected devices might notice extremely short battery life while on Wi-Fi. According to Sophos, that's mainly due to the worm engaging in "so much network activity."
When a device is infected, it's assigned a unique number so that the attackers can easily pinpoint a single device. It also looks for authentication systems that use SMS, better known as mTANs. mTANs are frequently used by banks that send an SMS message with a password to mobile phones, allowing people to log in to their online accounts, Sophos wrote.
In essence, this threat is serious.
Sophos recommends that people with infected iPhones and iPod Touch devices restore them back to Apple's most recent firmware update. For now, there is no other way to fix the problem.

Firefox has a CPU usage issue and, consequently, can cause overheating problems in some laptops, particularly ultraportables. That's what I've found over the last couple of years.
But don't take my word for it. This is documented on a Mozilla support page entitled "Firefox consumes a lot of CPU resources." The page states: "At times, Firefox may require significant CPU [central processing unit] resources in order to download, process, and display Web content." And forum postings like this one about a Dell Netbook are not uncommon: "Mini9 would get way too hot."
The Mozilla support page goes on to say that "you can review and monitor CPU usage through specific tools" and describes ways to limit CPU usage, such as: "A Firefox add-on, called Flashblock, allows you to selectively enable and disable Flash content on Web sites."
Let me describe my experience. I find that tab for tab, Firefox uses decidedly more resources than other browsers--Safari, for example. And in the past (when I was actively using a Windows Vista-based machine) Firefox also compared unfavorably with Microsoft's Internet Explorer for CPU usage.
More specifically, here's the behavior as I see it. When I'm accessing sites with multimedia content such as the CNET front door, Firefox CPU usage will bounce around between 30 and 60 percent, and sometimes spike higher (80 percent and above), as indicated by the Mac OS 10.6.2 Activity Monitor.
On the other hand, the Safari CPU usage with the same pages open is much lower--typically between 2 percent and 10 percent.
My theory is that most users don't notice this because in mainstream laptops, this isn't an issue. But it can become an issue in ultraportables--typically under an inch thick--which are more sensitive to heat because of the design constraints. The ultrathin Apple MacBook Air, which I use as my main machine, is a good example.
The fan is usually an audible indicator of CPU usage issues. When I'm using Firefox and I have tabs open on multimedia-rich sites (which is par for the course these days), the Air's fan will almost invariably kick on and stay on until I close the tabs. As I write this, the fan has finally shut down after I closed the Firefox tabs (e.g, CNET front door). Those same tabs in Safari are still open and not causing any significant spike in CPU usage or fan activity.
When I contacted Mozilla, a technical support person guessed that Safari is possibly better at optimizing Flash-based sites compared to Firefox. And that may be true. However, I had similar issues before when I was using a Hewlett-Packard business ultraportable (also very thin like the Air) that were not necessarily tied to Flash usage. In short, Firefox was less efficient with CPU usage compared to Microsoft's IE 8. And the behavior was similar. The HP laptop would quickly heat up and the fan would kick on.
Finally, let me reemphasize that I'm guessing that most users don't notice this because heat dissipation is not a big issue for mainstream laptops that are not necessarily thermally-challenged when accessing multimedia-rich Web pages. That said, this has been a steady problem for me because I use ultraportables almost exclusively and has forced me to limit my use of Firefox.
Internet Explorer 8, Firefox 3, Google Chrome 4, Apple's Safari 4, and Opera 10 include features that block sites known to host malware and malicious downloads. All but Opera also let you browse without leaving any tracks. But just as important as these protections is ensuring that whichever browser you use is thoroughly patched.
Filtering out bad sites
Firefox's built-in antiphishing tool claims to update its bad-site database 48 times a day, according to Mozilla's Firefox security page. Firefox 3 uses Google's Safe Browsing service to automatically block sites that are known to host malware. The Google Code site describes how Safe Browsing works in Firefox.
To verify that attack-site blocking is enabled in Firefox, click Tools > Options > Security and make sure "Block reported attack sites" is checked.
Firefox will prevent known-bad sites from opening when "Block reported attack sites" is checked.
(Credit: Mozilla Foundation)The same feature is built into Google's own Chrome browser. You can ensure that malware-site filtering is on in Chrome by clicking the wrench icon in the top-right corner, choosing Options, and selecting Under the Hood. "Enable phishing and malware filtering" should be checked. The Google Chrome Help site describes the feature. (Hint: This page looks very similar to the description on the Google Code site.)
Google's Chrome browser blocks known-bad sites when "Enable phishing and malware protection" is checked.
(Credit: Google)The SmartScreen technology in version 8 of Internet Explorer blocks known-malicious downloads as well as bad URLs. Other new security features in IE 8 include automatic blocking of click-jacking and cross-site scripting attacks, automatic crash recovery, and highlighting of the actual domain name in the address bar. The Microsoft Security site describes the SmartScreen Filter and includes links to a SmartScreen FAQ and information for site managers.
Apple's Safari browser added phishing and malware blocking in version 3.2, which was released in late 2008; read about this and other security features in Safari 4 on the Apple Safari site. Likewise, Opera's Fraud Protection predates the phishing and malware filters in IE and Firefox and is enhanced in the latest version 10. But attack-site blocking is only one of Opera's many security features, which you can read about on the Opera site.
Browsing in private
To activate private browsing in Firefox 3, click Tools > Start Private Browsing, or simply press Ctrl-Shift-P. You can set Firefox to start in private-browsing mode by clicking Tools > Options > Privacy and check "Automatically start Firefox in a private browsing session." The Mozilla support site provides more information about this feature. Likewise, put IE 8 in private-browsing mode by clicking Safety > InPrivate Browsing, or by pressing Ctrl-Shift-P. You can also open a new tab and click either Browse with InPrivate or Open an InPrivate Window.
IE 8 also lets you control the information about your browsing habits that's shared with Web tracking services. To activate this feature, click Tools > InPrivate Filtering Settings and choose "Let me choose which providers receive my information." This opens the InPrivate Filtering settings dialog, where you can turn filtering off, choose which services to block from tracking you, or automatically block all trackers.
Internet Explorer 8's InPrivate Filtering lets you block some or all Web tracking services.
(Credit: Microsoft)You can open an incognito window in Google Chrome by clicking the wrench icon in the top-right corner and choosing "New incognito window," or simply press Ctrl-Shift-N. The incognito icon (a shadow figure in a fedora and glasses) appears in the top-left corner of the browser window. The Chrome support site offers a more detailed description of this feature.
Opera lacks an equivalent private-browsing capability but does offer private searching and other identity-blocking features, as described on the Opera site. To activate private browsing in Safari, simply click Safari Settings Menu > Private Browsing.
Automatic and not-so-automatic browser updates
Patching is a way of life with nearly all software, but especially with browsers and the media players associated with them: Adobe Reader, the Flash Player, Apple's QuickTime, and Sun's Java, among others. All of a browser's security features can be rendered useless by a piece of malware that takes advantage of an unpatched hole in the program.
Firefox 3 alerts users to the presence of an update and now also notifies you when your Flash Player is out-of-date. Internet Explorer 8 updates via the Windows Update/Microsoft Update services. Google Chrome made a splash by being the first browser to update itself in the background without requiring any prompting from users. Safari updates automatically via Apple's update service, which also serves up patches automatically for QuickTime, iTunes, and other Apple software. Opera also notifies you automatically when a new version is available.
But updating is too important to leave to others. Back in April, I described Secunia's Online Software Inspector and downloadable Personal Software Inspector, which identify out-of-date programs on your PC. The programs mentioned in that post have all been updated since, but Secunia's services should point you to the most recent versions.
(Note that Secunia sometimes reports a program as being out-of-date when in fact you have the latest version. On my PC, it continually reports my up-to-date Flash Player as being in need of an update, for example. But the free service Secunia provides is worth putting up with this and similar minor annoyances.)
Trillian IM is finally available to iPhone users.
(Credit: Trillian)It took a few months, but finally, Trillian IM is available to iPhone and iPod Touch users through Apple's App Store. The application costs $4.99.
Cerulean Studios, the company that created Trillian, said that Trillian for iPhone sports several features users will already find on the company's desktop software. The app displays contacts, grouped and sorted by their respective categories. Users can also view multiple chat windows in a tabbed display. Thanks to updates Apple has made to the iPhone and iPod Touch, Trillian for iPhone also supports copy and paste. As with Trillian for the desktop, users can set their status, choose an avatar, and set up different status messages.
Because the app is always connected to Cerulean Studios' Astra server, users can synchronize content across multiple IM clients. In other words, any changes made on the iPhone version of the app will immediately be reflected on the company's Windows client and the user's Astra profile. Any contacts users add will also be synchronized with their other clients.
According to Cerulean Studios, all chats are maintained on the server, so they are kept in case of a lost connection. The app will also alert users when they receive an instant message, regardless of whether Trillian for iPhone is open or not. When an IM is received, users will see a dialog box, hear the Trillian IM-notification sound, and be able to start Trillian and reply to the person.
Those interested in using Trillian for iPhone will first need a Trillian Astra account. Luckily, the iPhone app allows users to sign up for Astra from within the app.
Apple quietly launched a new preview service this week that makes it easier for users to view its iTunes music library from the browser.
Dubbed iTunes Preview, the new feature allows visitors to view iTunes content from their browser without being forced to launch iTunes. Previously, when a Web user received an iTunes link, they needed to open iTunes to view its content.
As part of the launch, Apple has updated links in iTunes to redirect to iTunes Preview. When a user copies a link in the software and pastes it into the browser, they will be brought to the song's individual listing on Apple's Web site. The feature is especially handy for those who don't use iTunes, since they can now view an individual song without being forced to download the software.
Aside from individual music listings, iTunes Preview also allows users to sift through artists and albums based on genre. Each individual listing displays all the songs in an album, the album art associated with it, its cost, and other content typically found in the iTunes store. The page also includes a link to the iTunes store in case the viewer wants to buy it. That said, there aren't any song previews in iTunes Preview; users will still need to go to iTunes to hear them.

Apple released a security update for its Safari Web browser on Wednesday. Available for Windows and Mac, Safari 4.0.4 plugs what sound like moderate to severe security holes. Unlike competitors Internet Explorer, Firefox, and Chrome, Apple doesn't rate the severity of its security fixes.
The security fixes address a wide range of problem points. On both Windows and Mac, parsing maliciously written XML content could have led to a browser crash, using shortcut menu options within a maliciously created Web site could have led to the disclosure of local information, and visiting a maliciously built Web site could have resulted in unexpected actions on other opened Web sites.
For Windows only, viewing a maliciously made image with an embedded color profile that could lead to a browser crash or running arbitrary code is no longer a threat, nor is accessing a maliciously crafted FTP server, which could have led to an unexpected crash, information disclosure, or arbitrary code execution. For Mac only, an exploit that could have allowed e-mail to remotely load audio and video content when loading a remote image has been disabled.
Although it's good practice to update a program whenever a security fix has been released, more transparency from Apple on the matter would pull the company up to competitors' standards.

If you're a fan of comic books, you should also be a fan of the iPhone. Apple's smartphone is home to several neat comic-book apps designed specifically for those who want to enjoy harrowing stories of their favorite heroes in the Digital Age.
I've sifted through the many apps related to comic books and found a handful that you'll want to try out. Whether you're a DC Comics fan or you're partial to Marvel, I think you'll like what you find in these apps.
Get your comic on
Clickwheel Comic Reader if you plan to read comic books on your iPhone, the Clickwheel Comic Reader will be able to satisfy that desire.
When you start using Clickwheel Comic Reader, you'll be able to sift through comic books and find one you want to read. The app doesn't have many of the classics like those you would find from an app like Comics or iVerse Comics (see below), but it does have some comic books you might care about. Either way, the app displays all your favorite content in full color on your iPhone. And since it's free, it's probably worth trying out if you don't mind reading a relatively small collection of books.
If you want to read some comic books, Clickwheel might be your choice.
