Hi guys I have an original iPhone (aluminum) that won't boot. I used the reset functionality in the settings menu of the iPhone, and after that it got stuck at the black loading screen with a grey Apple logo. It seems that there is a loading-animation there aswell (half-inside the logo, frozen). I tried killing it (had to use the kill switch, couldn't just use the power button). The software on the phone is 3.0, and it is jailbroken. I tried connecting it to my Mac, but it doesn't pop up in iTunes. What can I do to get it up and running again?
