Hello! Need your help badly... I currently have a Iphone 3gs which has a 3.1.2, I wanted to upgrade it and jailbreak it. So, I downloaded 4.1 firmware from hackstore then i used redsnow 0.9.6b6 to upgrade it and jailbreak it... But what happened is that it goes off and on... (black screen with apple logo). Help! What should I do? The phone is unusable... Note: It disconnects by itself when plugged to the computer. Im currently using Windows 7.
