iPhone and iPod touch Get Firmware Update v2.2.1

“Apple has issued a new firmware update for your iPhone and iPod touch. You can get it right away but it won’t get you any spectacular features. Version 2.2.1 improves stability and fixes some bugs. But here’s a list with the most important updates:
– Improved general stability of Safari
– Fixed issue where some images saved from Mail do not display correctly in the Camera Roll
– Fixed issue that caused some Apple Lossless (ALAC) audio files to skip during playback [iPod touch]
Just bear in mind that unlocked and jailbroken phones shouldn’t get nowhere near this update yet. Who knows what might happen?!” via mobilewhack.com
