While we are surfing Tweets of the famous iPhone hacker MuscleNerd , we we have found a really interesting information.The iPhone Dev Team is close from release the solution to downgrade iPhone 3GS baseband from 6.15.00 to 5.13.04 to fix to fixGPS problem on iPhone 3GS.
One of MuscleNerd followers asked him about any updates about downgrade 6.15.00 to fix GPS problem:
jntacid : men any news about 06:15 downgrade, i need my nike+Gps
MuscleNerd:there’s a good reason to not release anything like downgrade that before iOS5 (though sometimes I think I overthink it!)
So that, it’s highly expected that downgrade 6.15.00 baseband to fix GPS problem is almost completed, but as usual all hackers are holding their major hacks, jailbreaks and unlocks after iOS 5 release to keep them away from Apple hands.
