Apple has released iOS 4.1 for iPod Touch and iPhone devices.

OS 4.0.1 for iPhone and iPod Touch is rolling out to devices right now. iTunes has been prompting users to update to the latest iteration of their mobile operating system. iOS 4.1 is available for iPhone 3G, iPhone 3GS, iPhone 4, iPod touch 2nd generation, iPod touch 3rd generation, and iPod touch 4th generation.

iOS 4.1 includes fixes for the iPhone 4 proximity sensor, iPhone 3G performance and bluetooth issues. The new mobile OS also includes a new game center to allow multiplayer games to be more social. iOS 4.1 users can also take HDR pictures, rent TV shows from iTunes and upload HD videos to YouTube. Apple is expected to release iOS 4.2 in November for iPhone, iPod Touch and iPad.

We have to point out, DO NOT to UPDATE your version 4.1 for now, as per the DevTeam suggestion:

This time of year there are lots of new iPhone owners, and not everybody knows that accepting new iOS updates is the surest way to lose your jailbreak and/or unlock.  While those of you who have Cydia or TinyUmbrella backups of your FW hashes will always be able to get back to 4.0.1 if you make this mistake, this doesn’t hold for unlockers. There’s currently no known way to revert your baseband — if you update your baseband you’ll lose the ultrasn0w unlock, possible forever.

Please stay away from this 4.1 release until a safe jailbreak procedure (which also preserves ultrasn0w) is developed and released.

P.S.  There are a very few iPhone3G owners who can revert their basebands due to a flaw in very early bootloaders…you will already know if you fit in this category!)
