Hi. I've jb my iPhone 4, ATT USA. It had iOS 4.0.2 with 01.59.00 modem originally, I've used snowbreeze in baseband preservation mode to upgrade to 4.3.1. Then I jb it using redsnow rc9. Through Cydia installed ultraslow 1.2. When I insert a SIM it shows 1 bar and there is no carrier tab in settings. Other times it shows no network, and still no carrier tab in settings.

If I go into about iPhone section it says iOS 4.3.1, operator ATT 10.0, modem 01.59.00

Please help!

Edit.. Here is the fix; Fix No Service after ultrasn0w 1.2 on 6.15.00 / 01.59.00 iPhone 3GS / iPhone 4 problem - Redsn0w

Congratulate a brand new owner of jailbroked and unlocked iPhone 4. Tomorrow I'm going to buy a micro SIM and a new number, put a few rubles on it, and party putin style!!
