The iPhone 4S on Verizon offered a good balance between call quality and data speeds during travels in California.

Question: Which is more important, call quality or data speeds? Let me state my bias up front: The Web running on 3G is really important to me. On any device. Whether it's a MacBook connected to a MiFi hot spot, a 3G iPad 2, or an iPhone. That said, is it important enough to justify sacrificing voice call quality?

This week I spent a lot of my time obsessing about the Web performance of my new Verizon iPhone 4S during … Read more

Opera Mini 6.5 brings this version of the alternative browser to iOS devices (version 6.5 has been available for Android for three weeks at the time of this review). We have had a chance to put the slimmed-down browser through its paces and it offers several features we think users will like. With the right tweaks, it may even become the favorite over Apple's Safari--if people are willing to give it a try.

The clean, elegant interface hides multiple useful features, with only five buttons to choose from, along with the address bar and search box. The … Read more

Glaryutilities' Disk SpeedUp is a free standalone utility that analyzes, defragments, and optimizes your disk drives or individual folders. It offers manual and automatic defrag options as well as automatic shutdown after defragmenting finishes.

Like many system utilities, Disk SpeedUp has a colorful interface with large, clearly labeled buttons and tabs labeled Defrag Show and Settings. The Defrag Show tab showed our two disk drives and their capacity, free space, status, and percentage of fragmentation. In the middle was a standard defrag map, while at the bottom of the interface, Disk SpeedUp displayed tabs with our three partitions, each with … Read more

Sprint and Apple are said to be working on a possible software fix for slower-than-expected wireless networking speeds affecting some users of Apple's latest iPhone.

The issue has been the topic of a now 60-page support discussion thread on Sprint's site that began the day the phone was launched. There, users have been complaining of slow 3G speeds and posting photos of speed tests, including ones showing differing handsets to suggest the problem is limited to Apple's recently launched iPhone 4S hardware.

The Next Web today points to an alleged internal memo making the rounds to Sprint representatives saying that both Sprint and Apple are both aware of, and working on, a fix, suggesting the problem could be software-related. … Read more

As freeware system cleaners go, Magix PC Check & Tuning Free offers a good balance. Some such tools are designed to be as easy to use as possible and give you few options and not enough information about what they're doing to your system. Others overwhelm beginners with options and detailed scan reports, and they often make it too easy to delete the wrong things. The freeware version of PC Check is designed to be easy to use yet useful to people with widely varying skills, yet it also lets you perform cleaning and tune-up operations separately as well … Read more

It's one of the last mutually exclusive genres left in gaming. PlayStation owners have Gran Turismo and Xbox 360 loyalists have Forza Motorsport. Both franchises are proven winners, and the latest incarnation on Xbox 360 allows Kinect users the chance to race controller free. But does that ambition steer Forza away from what it does best?

Jeff:Forza Motorsport 4 packs in such a shocking amount of content and detail, most racing buffs will salivate just at the introduction movie. Sure, it can be a bit overwhelming for people who don't have transmission fluid running through their veins, … Read more

Along with my review copy of Forza Motorsport 4, I was sent an example of Microsoft's Wireless Speed Wheel to test with the game. As a car guy and a bit of a racing sim snob, I initially viewed this wireless, motion sensitive plastic bauble down the bridge of my upturned nose. By the end of the weekend, the Speed Wheel had won me over.

Normally, I do my racing simulation from behind a proper racing wheel with 900 degrees of rotation; belt-driven force feedback; the choice between paddle, H-pattern, or sequential shifters; a trio of pedals; and an aluminum adjustable stand to hold it all together. The whole kit weighs about 30 pounds and takes me about 10 minutes to drag from its place in the bottom of my closet and set up, but once it is, the driving experience is spectacular. Surely the wireless wheel can't do better?… Read more

Temple Run is a survival/escape game from the makers of Harbor Master in which you play as a character who's a lot like Indiana Jones from the popular action movies. The simple storyline is that you've stolen a cursed golden idol, and now you need to run for your life from demon guardians through all kinds of obstacles. A little different from the other games in this genre, Temple Run gives you a 3D perspective as you run, jump, turn, and slide down pathways while grabbing coins. You'll definitely want to grab as many coins as … Read more

European physicists have measured tiny particles called neutrinos moving just faster than the speed of light--only a smidgen faster, but enough to raise a serious possibility that Einstein's physics need a major overhaul.

The scientists sent a beam of neutrinos from CERN, on the Swiss-French border near Geneva, to the INFN (Istituto Nazionale di Fisica Nucleare) Gran Sasso Laboratory in central Italy, 730 kilometers (454 miles) away, in a research project called OPERA. The physicists had planned to study a rare event, the transformation of the muon variety of neutrinos into the tau variety. Instead, they found the extraordinary … Read more
