SkankPhone is a part of Apple's internal debug utilities suite. It can be defined as a SpringBoard alternative. Instead of dividing the iPhone OS functions such as Phone, Safari etc. into standalone applications, Apple developers combined many functionalities into one app. SkankPhone has a integrated phone, web browser, music player and SMS editor. In Alpine_1A420 prototype firmware it also has a built-in Operator screen.
