Entering Recovery Mode
- Turn the device completely off and disconnect it from cable/dock.
- Hold down the home button.
- While holding down the home button connect to a computer with a cable (easiest) or dock.
- Keep holding down the home button until you see a connect-to-iTunes screen (on a QuickPwn'ed phone a drawing of Steve might be shown). You are now in recovery mode.
To escape Recovery Mode and power the phone off simply hold down power and home buttons for ten seconds.
Note: This method not works in iPhone 2G.
