I have a 3GS with 06.15.00 baseband. I was on 4.3.1 before I updated to iOS 5 today. After updating to iOS 5 my iphone couldn't activate. I downloaded RedSnow 0.9.9b4 to jailbreak and activate my phone. My jailbreak apparently seem to go thru fine however the process seems to get stuck during reboot and screen freezes. Can someone please guide me thru and let me know how to either restore it back and activate or hactivate?
