  • Warning: ultrasn0w May Break GPS on Baseband 6.15.00


    The Dev-Team is warning about a potential issue with ultrasn0w for iOS 4.2.1 on iPhones with the 06.15.00 baseband. An increasing number of users with that version of the baseband software are reportedly losing GPS functionality when they unlock their device. The blog post says they are looking for the root cause but haven't found it yet, and notes that it's not a problem for all or even most users with that baseband. Still, to be on the safe side, they're suggesting people should just not expect GPS to work if they want to unlock iPhones with the 06.15.00 baseband using ultrasn0w:

    Update #5: Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume youíll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks donít work).

      You'd use ultrasn0w to unlock and no your gps won't come back. It is broken as long as the baseband has been upgraded to 6.15.00

      Could it be fixed if a new baseband came out?

      If a baseband with a higher version was released by Apple that would most likely fix it. But it would also relock the phone.

      The BB in the latest beta is 04.11.08 and it's unlikely to change much so I wouldnt hold your breath.

      That's the iPhone 4 baseband. Although I think the baseband for 3GS is still in the 15's so what you said is still correct.
