I have jailbroke / unlocked 3G iphone. Was having some issues with unresponsive screen ie couldn't slide unlock button and keyboard not working but typically ok if I pushed sleep then home button. When Blackra1n became available I upgraded to 3.1. Same issues persisted until finally there is no response. I tried to re jailbreak and unlock and nothing (in large part due to the fact that I couldn't complete the unlock because I can't use the screen). I've done several resets and 2 restores. Screen still is unresponsive. 2 questions - are there any options that I can try at home? And is there a way to go back to apple and receive support from them - possibly by relocking the phone? THANK YOU SO VERY MUCH!
