Hello Jaxov team, I have just jailbroken my iPhone 3GS on iOS 5 using the latest version of Redsn0w. My iPhone is running iPad baseband 06.15.00 and I have already installed Ultrasn0w from Cydia but unfortunately my iPhone still seems to be locked to AT&T. Can anyone please help me to get it unlocked? Thanks in advance.

Additionally, make sure that you have activated your iPhone using iTunes after jailbreaking and unlocking it. You can activate your iPhone using iTunes by inserting the original AT&T SIM card, or you can use SAM app to activate your iPhone. You can refer to this guide on how to activate iPhone using SAM app.
Lastly, in most cases, re-flashing of the iPad 06.15.00 baseband on jailbroken iPhone 3GS is necessary. So I would recommend you to reflash your baseband using Redsn0w and then reinstall Ultrasn0w 1.2.4. Good luck!
