ZiPhone 2.0 GUI

From Developer site:

ZiPhone v2.0 is finally OUT.
In the command line version, you will find a new
option "-b" be very careful with that!
I take no responsability if you brick your phone!
ZiPhone -b will downgrade bootloader from 4.6 to 3.9,
flash 4.03.13_G baseband version and
unlock it (in one shot!).

MAC GUI

From MMI:
This jailbreaks any iphone with 1.1.3 firmware. It will unlock and activate 1.1.3 iphones with the 4.6 bootloader (1.1.2 and 1.1.3 OTB iphones). Very easy, one-click solution - couldn't be easier!
This works on Apple OS X (Intel + PPC).
