I have a iPhone 3G. So I made the mistake of upgrading to 3.1.3 firmware, I had unlocked and jailbroken with Cydia and Blackra1n. So i waited a while until there was some ways to do it to 3.1.3 and used Redsn0w to jailbrake which worked and tried to unlock with Sn0wbreeze and it didn't work, I then turned the phone off and the next day I have turned it on and I think its bricked. It just has the sn0wbreeze symbol, computer wont recognize its plugged in and I have held down hold and home to rest and it does nothing. Anyone in the same position or know how to fix it!?
