iPhone unlocking is a very popular feature because naturally, it allows iPhone users greater freedom and enables them to user their devices across other, unauthorized networks. Ultrasn0w is probably the most popular tool used to unlock iPhone because it is really easy to use.
Currently, five basebands of iPhone 4/3GS are supported by Ultrasn0w. Among these is 06.15.00 which iPad users must upgrade to if they want to unlock their tablet. However, one of the major problems with this baseband is that it renders iPhone’s GPS quite useless.
However, the good news are that the solution to this problem may soon be here. The solution will be that users will finally be able to downgrade their device from 06.15.00 to any other baseband. And this has now been divulged by none other than the notable iOS hacker, MuscleNerd.
According to him, he has been working on such a tool and that he has made significant progress. This pretty much means that we are only days away from a new version of Ultrasn0w which will allow users to downgrade from 06.15.00.
For such users who are using the said baseband on their iPhone 3GS and iPhone 3G devices, this is a great piece of news. Soon, they will be able to enjoy a far greater freedom on their devices and will be able to utilize GPS navigation too.
