eBay may have recently sold off Skype to the highest bidder, but the VoIP app for desktop and mobile is still in development.

On Thursday, Skype announced Skype 4.2 for Windows beta and a new beta build for Symbian phones. Skype 4.2 beta for Windows desktop users is small as updates go, reinstating Skype Access--a Wi-Fi hot-spot connector--and call transferring that Skype had removed when overhauling its app and updating to version 4 (now in version 4.1), a build that includes screen-sharing.

You can scrutinize the full release notes here.

In addition to tightening up Skype for the desktop, the company announced it will issue a limited beta release for Symbian Series 60 handsets. There's compatibility for 17 Nokia handsets at launch, with use on more phones on the way.

The feature set is basic at present, with just the following features in place:

• Free Skype-to-Skype calling
• Call phones with Skype credits or subscription
• Receive calls on your online number
• Instant messaging
• Group conversations
• File sending and receiving

The new labels for different versions of HDMI cables.

If you've caught yourself scratching your head trying to figure out what type of HDMI cable to buy, you're probably not alone. With so many versions, it's hard to know which does what. However, very soon, you won't have that trouble anymore.

In an effort to make it easier for customers to identify the right products for their needs, HDMI Licensing released Thursday, on behalf of the HDMI Founders, an updated version of the HDMI Adopted Trademark and Logo Usage Guidelines. HDMI Licensing is the agent responsible for licensing the high-definition multimedia interface specification.

The most notable changes in the guidelines are significant restrictions on the use of version numbers and new marketing requirements for cables. These new requirements are designed to simplify the product selection process for consumers, enabling them to purchase an appropriate product based on features, instead of having to do research on what each version does.

According to the new guidelines, adopters will no longer be allowed to use HDMI specification version numbers in the labeling, packaging, or promotion of their HDMI-compliant products. These restrictions go into effect immediately for cable products. Noncable products, however, have until January 1, 2012, to fully comply.

The new guidelines designate all HDMI cable products into five types:

Earlier this week, Asus unveiled a 15-inch laptop with Nvidia's 3D Vision technology built in. The $1,699 Asus G51J 3D has a 120Hz LCD panel, an Intel Core i7 CPU, and a high-end Nvidia GeForce GTX 260M GPU, and comes bundled with a pair of Nvidia's active glasses and the USB-powered IR emitter required to make the glasses work.

We've just had a chance to take the system for a test drive, and came away largely impressed with the results, especially compared with Acer's Aspire 5738DG, a 3D laptop that uses a pair of passive polarized glasses and a special screen coating to create a 3D effect.

That Acer model was unfortunately underpowered for gaming, especially with the added overhead of running its 3D software in the background. The Asus G51J, on the other hand, with a high-end processor and video card, seemed well-suited for mid-to-high-end gaming. Of course, it lacked dual SLI video cards and the 1,366x768 15-inch display is no match for some of the nicer 17-inch 1080p displays we've seen.

While playing Left 4 Dead 2, the 3D effects appeared crisp and appealing, and didn't seem to distract from the speed of gameplay or the screen brightness. There appeared to be no real hardware burden in generating the 3D in terms of frame rate or graphics detail, either. On the other hand, the 15-inch screen is a little small as compared to a nice big gaming monitor, and that mitigated the overall immersion of the 3D effects.

The bigger problem is that 3D gaming is still a novelty. It's not actually needed to appreciate any game at this point, and it has an expensive and often clunky set-up for users to navigate through.

Many people haven't even seen 3D of the caliber that Nvidia is currently offering, and so they have no idea how smooth and crisp it is compared to the fuzzy double-vision experience of years past. What's particularly great about Asus' solution is that it's already integrated into a reasonably priced Core i7 gaming laptop, so the set-up and research into compatible hardware components is almost entirely eliminated.

This is an interesting trend to watch for in gaming laptops, and it should be included in more Core i7 laptops aimed at gamers, especially if Nvidia is serious about getting a larger adoption. We expect to see more 3D Vision capable laptops from major PC makers by early next year.

Last week's launch of a certain game may have eclipsed the first-person shooter landscape for some time, but there are other gripping, visceral shooting experiences to be had at the tail end of 2009. Last year's Left 4 Dead found Valve adapting its skill at multiplayer online gaming to a co-op grindhouse-style horror genre, one in which cooperation played more of a factor than lone-dog competitiveness. While the original Left 4 Dead had only four campaigns and was a chiefly online experience, it sustained some criticism for being too short and for not having more multiplayer modes.

The new Left 4 Dead (we played the Xbox 360 version) has only five campaigns--one more than the original--but they proceed through much larger, far more interesting zones, all set in the deep South. Heavy thunderstorms, a bizarre carnival, and lots of swampy backwaters add great environments. On top of that the game features additional infected zombie types, weapons, and items to acquire, all of which make the game more unpredictable and diverse--our one complaint with the original was that it started to get a little repetitive over time. Shoulder-riding Jockeys are the best of the new, while fast and cruel Chargers seem to pummel too quickly. The new Infected can also be controlled in Versus mode, adding new playable characters.

Also new are a collection of chainsaws, frying pans, and other hard-core bludgeoning weapons. They aren't always the most efficient tools, but they feel great to use and can cut through Left 4 Dead 2's zombie swarms better than rifle-butting. There are also new items like the adrenaline boost to speed up play.

We had as much fun, or more, playing the sequel than we did the original, although the graphics and general feel don't fall far from the zombie tree. ... Read more

The final expansion pack (or episode) for Grand Theft Auto IV has been released in the form of The Ballad of Gay Tony. You assume the role of Luis, nightclub owner Gay Tony's right-hand man who must handle his dirty work across Liberty City.

The Ballad of Gay Tony can be downloaded via Xbox Live (for $20) or in a $40 disc form (called Episodes from Liberty City) which also includes The Lost and Damned, GTA IV's first additional episode.

We've had sometime with the final version of the game and here are our thoughts:

Jeff:
First thing's first. If you haven't downloaded The Lost and Damned, go out and buy Episodes From Liberty City. It's tough to recall such a great value in gaming prior to this double pack, and Xbox 360 owners don't need a copy of the original GTA IV to jump right in. There is an incredible amount of gameplay value here; it's like getting two full $60 games for less than the price of one.... Read more

Russ with Hova--no big deal.

Russ Frushtick from MTV's Multiplayer blog joins us on today's episode of The 404 Podcast to give us the rundown of this month's upcoming video game releases, but first we have to give a quick head nod to the Yankees for winning the World Series and, of course, Matsui for coming through with the MVP of the series.

Also, were you as annoyed with the lame tech commercials during the game as we were? Between James Cameron's upcoming flop "Avatar" that looks like a 2-hour video game cut scene, the new Droid phone ripping Apple apart, and the rather malicious new Mac ads practically lying about past versions of Windows, we could barely watch the game!

Next, we run down a list of near-extinct tech that just won't seem to go away. The list includes items like the landline telephone, Twitter, vinyl, fax machines, Windows XP, and Sonic the Hedgehog, and although we agree with most of them, how are people supposed to send sandwiches to loved ones without a fax machine?

By far, the highlight of today's episode comes toward the tail end of the show during our classic Calls From the Public segment, where Jeff is the reluctant receiver of a huge spoiler to his current read, Lois Lowry's "The Giver." If you're planning on reading the book for the first time, you might want to click the mute button for the remainder of the episode, or risk suffering a similar fate. On the other hand, the look on Jeff's face when things get spoiled is too hilarious to miss.

The Audioengine P4 is a cheap speaker.

Correction, it's an audiophile speaker that sells for $249 a pair. But that hasn't stopped it from getting raves from audiophiles who live with speakers that sell for a whole lot more.

I use Audioengine A2 self-powered speakers ($199 a pair) with my computer, so I thought I had a handle on what to expect from the P4.

The review P4 speaker sported a real, solid bamboo cabinet, wow!

I did not; it's a whole new ball game. First, the P4 is a "passive" speaker, so you need to hook it up to an amplifier or receiver. The A2 is an "active" self-powered design that can be connected to a computer or MP3 player via a headphone jack.

I started listening to the P4 with my computer, with the speakers hooked up to an old Jolida hybrid tube/solid-state amplifier. The A2 is a sweet sounding little speaker, but the P4 was dramatically clearer, cleaner, and more vibrant. The P4 blows the A2 away--it's not even close.

At 9 inches tall by 5.5 inches wide by 6.5 inches deep, the P4 looks like a larger A2 (the A2 is 6 inches high by 4 inches wide by 5.25 inches deep). The P4 comes in satin-finished black or gloss white paint for $249 a pair, or in bamboo for $325 a pair. The wood isn't merely a veneer over medium-density fiberboard; no, the P4's cabinet is made out of solid bamboo, it's gorgeous!

Audioengine offers a nifty tabletop stand, the DS1 ($29 a pair), that cants the speaker back at an angle to project sounds up. The rubbery stands also isolate the speaker and prevent it from transmitting bass into your desk. Want to wall mount it? No problem, use the threaded inserts on the speaker's rear-end.

The P4's three-quarter inch silk dome tweeter and 4-inch Kevlar woofer appear to be of very high quality. Both drivers are made by Audioengine.

The Klipsch Image S4i earphones are nearly identical to their sibling, the Image S4. They not only provide the same comfortable fit and stellar sound quality, but also offer the added bonus of an integrated mic and call answer button, as well as volume controls and remote playback for the iPod. Call quality through the inline mic is solid, though not overly spectacular for a wired headset. At $99, the Image S4i costs $20 more, which is probably worth it for those with an iPhone. For more information, read our full review of the Klipsch Image S4 headphones.

Everybody's all smitten with smartphones, but what if you don't want to be interrupted with a call while you're listening to your music? What if you don't want to risk your precious and expensive smartphone at the gym? What if you want to carry every song you own in one player? If this describes you, take a look at our top 5 best MP3 players. They play some video, but mostly they play music. Sweet, sweet music.
