All iPhone Unlockers, Stay Away from iOS 4.1 Until Further Notice
iOS 4.1 has just been released by Apple for iPhone 4, iPhone 3GS, iPhone 3G and iPod touch 2nd and 3rd gen. Those of you who currently rely on an unlock MUST STAY from iOS 4.1 until any further notice. Updating to iOS 4.1 might result in update of baseband, which will potentially lock your phone. You wont be able to unlock it until a new exploit is found again.
I am currently testing iOS 4.1 and will report back as soon as I have more on it. Stay tuned !! – YOU HAVE BEEN WARNED !
UPDATE 1: DO NOT update to iOS 4.1 if you rely on an unlock. Doing so will lock your device. You can jailbreak iOS 4.1 Beta on iPhone 3G (which doesn’t rely on carrier unlock, and iPod touch 2G (non-MC model) using Redsn0w 0.9.5b5-5. Follow the guide posted here to jailbreak iOS 4.1 on iPhone 3G, and here to jailbreak iPod touch 2G (non-MC model).
