MuscleNerd achieves iPhone 3GS downgrade from BB 06.15.00 to 05.13.04
Good news for iPhone 3gs owners, as you are aware yesterday Musclenerd tweeted that he is very near to downgrade iPhone 3gs from 06.15.00, and now few hours ago he tweeted that he has downgraded the first ever iPhone 3gs from baseband 06.15.00 to 05.13.04.
If you are not much aware of the benefits of baseband downgrade, this means that if your iphone 3gs is officially unlocked and upgraded to 6.15.00 for the unlock, now you can downgrade back to the baseband 5.13.04, which means that you will be able to unlock via ultrasn0w and the GPS will work even after unlock and iphone 3gs jailbreak.
thanks again for the extended loan of your 06.15 3GS…it ended up being the first ever 3GS to get downgraded to 05.13.04
