iPhone 3GS, version 3.1.2, firmware 05.11.07, old bootrom, successfully jailbroken with Blackrain and unlocked successfully too. Its perfect without any problems until last month, June 22, 2010. The problem arises last June 22 when it became hot, lose the wifi signal, then freezed, and totally lose its network signal. After it, the screen became black and stuck in apple logo turning on and off. I tried to restore in iTunes 9.0 but nothing happened. Cant go out from that apple logo, so i tried to restore in iTunes 9.2,,, and thats the only time it functions again and at the same time updated to iOS4 with firmware 05.13.04. No more jailbrake and i think not unlocked too. NOW my iPhone 3GS is version 4.0 (8A293), Modem Firmware 05.13.04, Old Bootrom. It was updated with iTunes 9.2 My question is,,,, CAN I JAILBREAK USING SNOWBREEZE IN WINDOWS 7??? Am I Stuck Out of Luck now??? THANK YOU IN ADVANCE!!!
