How to Downgrade From iPhone Firmware 2.2

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.

iPhone Firmware 2.1 Release Coming Friday

The next iPhone firmware update will be released this Friday, according to Steve Jobs at Apple's Let's Rock event in San Francisco. The new version will include fixes for many ongoing problems reported by users in version 2.0.1 and 2.0.2. On the list of fixes is a solution to the application crashing problem, battery life improvement, faster iTunes backup speeds, and other bug fixes.

In addition, firmware 2.1 is purported to solve many connectivity issues and reduce the number of dropped calls. The download will be free for iPhone users, although iPod Touch users who haven't already upgraded to 2.0 will have to shell out $9.95 for the upgrade. Along with the firmware, iTunes has been updated to version 8.0 and is already available for download.
