From the developer:
Use Reiboot to exit Recovery/DFU Mode when iDevice gets stuck into Recovery Mode (red iTunes logo/USB cable) or DFU Mode (black screen). The program helps you when you need to update to a new firmware, or downgrade to an older firmware. Use ReiBoot to put iDevice into Recovery Mode or DFU Mode with a single click, saving you from going through three or more steps manually with iTunes.
