Many users have been reporting problems with the iPhone firmware 2.2 upgrade from Apple. It may be that the best way to solve these problems is to take a step back and downgrade to firmware 2.1. Others inadvertently upgraded their phones when syncing to iTunes on their computer and for whatever reason would like to revert.

The process is relatively simple and should bring back the 2.1 version OS to your iPhone. Performing these steps on an iPhone 3G may work, however this article does not cover reversing the 3G baseband update included in firmware 2.2. Remember, taking these steps is at your own risk, and any hacking of the iPhone could render your remaining warranty invalid.

So you've watched the videos and looked at the photos of iPhone 3G disassembly and now you're ready for action. The glass screen is cracked and/or the LCD is broken and you have no intention of spending days without your device and paying Apple $200 or more. Although the do-it-yourself attitude is noble, it could cost you even more money if you're not careful. The tutorials above are a good start, but more details can only help.

Take these tips to heart if you're going to fix the screen yourself. First and foremost don't ever buy the glass alone (typically $20). It's useless. The digitizer can't be detached from the front glass. The next best option is the front glass and digitizer together (around $60). The LCD is mounted with screws behind the digitizer and runs $80-90. Remember, you perform this repair at your own risk, and will render any remaining warranty invalid.

Amongst the Black Friday mayhem Zagg, makers of the invisibleSHIELD, have announced today what just may be the best set of iPhone earbuds released to date, the Zagg Z.buds.

The good folks at our sister site, unwir3d.com, have scoured the world of Black Friday and Cyber Monday deals to pick out this year's best deals. Not many stores advertise their Black Friday sales before the day itself arrives, because they usually have a plethora of other sales going on in the preceding days, and they wouldn't want you waiting around for a better deal. This electronics-themed list, however, has managed to dig up some of the best deals around for the start of this year's holiday shopping season.

The deals pretty much cover the electronics spectrum, including HDTVs, laptops, digital cameras and other must haves. One of the more notable deals (hence number one) is the 50 inch Panasonic Viera HDTV. unwir3d found that NewEgg will be selling this 1080p beast for just $1399, which is almost 50% off its list price of $2699. Another gem is the Nikon D300 DSLR. This 12.1 megapixel camera will be $1324 on

Hot on the heels of the latest iTunes update (8.0.2) the latest iPhone firmware (2.2) was released early this morning. It appears there are some pleasant surprises, as some unexpected features have been added, including a 3G baseband update. This update will not affect first generation iPhones but promises to reduce dropped calls and call setup failures on 3G models.

Other unexpected improvements include improved sound quality of Visual Voicemail messages, enhancements to Mail, and a new use for the Home button. Now from any Home screen pressing the Home button will display the first Home screen. This is a simple change that will cut down on tiresome swipes between screens.
