Alpine 3B48

This is a factory firmware based on iPhone OS 1.1.2. It appears to be a newer version of Alpine 1A420, featuring a newer version of SkankPhone with the built-in Operator screen. It also has the ability to exit SkankPhone and boot into SwitchBoard.app, where one can find the following applications:


 * ATCommand
 * BurnIn
 * Operator
 * Rumble
 * SkankPhone
 * Soundwave

This firmware was originally spotted on a 2007 iPhone PVT but has since been seen on multiple devices.
