Apple has just pushed out Firmware 2.2.1 for iPhone and iPhone 3G, iPod touch, iPod touch 2G. You can download them here ^[1]. Firmware 2.2.1 cannot be jailbroken at this time, so unofficial application users should wait for new version of QuickPwn from DevTeam. Unlock (yellowsn0w) also doesn't work for 2.2.1.

This update contains bug fixes and improvements:

• Version 2.2.1 (Build 5H11)
• Modem Firmware 02.30.03
• 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) to skip during playback
• Unofficially Apple fixed SMS bug: users suddenly experience inability to send SMS text messages on the iPhone 3G, receiving the message "error sending" upon attempting to send.
