As Apple released new update of iOS, which is now iOS 4.0.1, this version was believed to fix the antenna reception issue but it wasn’t the case though, Steve Jobs lied again. While talking about this update Apple doesn’t focused on baseband, I means in iOS 4.0.1 the baseband is same as the iOS 4. Devices running iOS 4.0.1 are having 05.13.04 baseband.
This is pretty good for the jailbreakers or unlockers you can say. Yes guys with release of iOS 4.0.1, Ultrasn0w 0.93 comes into play. Ultrasn0w 0.93 is again able to unlock the new OS. Well you can’t say that the new OS is perfect, but Ultrasn0w is still able to unlock iPhone 3G.
You can find the steps to unlock iOS 4. As I have already given all the steps to unlock iOS 4 so it is no more worthy to repeat those steps again and again. These steps are easy enough to unlock your iDevice, for time being it only support iPhone 3G. Ultrasn0w 0.93 is also able to unlock those devices having 05.12.01 and 04.26.08 baseband. Here are the steps.
I just got a breaking news that Ultrasn0w has unlocked iPhone 4 as well. This is certainly a great for iPhone 4 fans that unlockers have unlocked it yet again, courtesy to MuscleNerd. Yes! Ultrasn0w is now able to unlock iPhone 4. Above is the screen-shot depicting the unlock.
