iPhone Dev Team Warn Jailbreakers And Unlockers To Avoid Upgrading To iOS 4.1

iOS 4.1

Apple is expected to release iOS 4.1 sometime today.

iPhone Dev Team has issued another warning to users who want to jailbreak and unlock their iPhone to stay away from iOS 4.1.

iOS 4.1 includes fix for the proximity sensor, Bluetooth and iPhone 3G performance problems and some major features such as HDR photos, HD video upload, ability to buy TV show rentals and Game Center, Apple’s social gaming network.

In a blog post, iPhone Dev Team have explained the reason for staying away:

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 tiny number of 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!

We’ll let you know as soon as we’ve any further updates. So stay tuned here at iPhone Hacks or follow us on Twitter or subscribe to our RSS feed.
