Hello guys ! My iPhone 3GS 6.1 baseband 06.15.00 doesn't seems to recognize my SIM card. I did the following steps but I don't understand what's wrong. 1- Updated iPhone 3gs on iTunes from 4.3.3 to 6.1 2- Used redsnow to bypass activation (hacktivation) and jailbreak Tethered 3- Installed evasi0n on cydia (jailbreak now untethered) 4- Installed ultrasn0w 1.2.8 (with mobile substrate) 5- Turned off the iPhone 6- Install sim card 7- Turned on the iPhone I still get no service. Anyone solved this problem ?

Here the best solution:
1- downgrade to 5.1.1 (using the latest version of resn0w ==> extra==>even more==>restore==>select IPSW==>Remote and wait till restoring finish)

2- jailbreak 5.1.1 (using redsn0w extra==>select IPSW==> back==>jailbreak and wait untill it finish)

3- Downgrade baseband to 5.13.04 (using redsn0w extra==>select IPSW==> back==>jailbreak==> uncheck cydia + check downgrade baseband)

4- in cydia install ultras0w

and this is it

if you want to work with 6.1 you should preserve baseband
