ZiPhone allows you to easily software unlock your iPhone. No hardware modification is required.

Release notes:

ZiPhone v2.0 is finally OUT. n the command line version, you will find a new ption “-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!).

It worked for me on 2 ootb 1.1.2 phones. It will work on 1.1.3 ootb phones too. Other options are unchanged.

Do not forget to donate! The future of ZiPhone will depend on you also! If you can’t code, or contribute in other ways, just donate.

I think we won’t need another version till the next firmware release 🙂

Peace out.
(To quote my favourite blogger)

For people who get stuck on apple logo.
Try to use: ZiPhone -v -b

That solved the problem for many people.
