I jailbroke my iPhone 3gs tonight, my first time jailbreaking an iPhone, and it was working fine until I tried to install Intelliscreen. I did not check to see if it was compatible with 3gs first and well, it isn't. It froze after I clicked Reboot Springboard so eventually I plugged it into iTunes and did a restore. After reboot iTunes says it cannot read the contents of the iPhone and to do a restore. I tried putting the phone in DFU mode and restoring but I get the same error. I just rebooted my laptop in case that will help and am doing another restore now. Should I try loading on the jailbreak firmware instead? What else can I do?
