From the developer:
Jailbreak, activate and desimlock iPhone and iPod touch with a clear interface.
Starting with version 2.4, Ziphone provides a simple all-in-one interface or a separate
advanced interface for experts or for people who needs more control over the jailbreak
process. Users with AT&T or other "legitimate" iPhone carrier SIMs may wish to use the
advanced interface in order to retain their own real activation tokens.
