UPDATE : Download ZiPhone Latest Release for Windows. A Mac version of the same can be had here.

ZiPhone GUI is built by i.unlock.no which is based on GeoHot’s unlock script which was generalized by Zibri ZiPhoneGUI is for Windows users while Mac users have a better application in the form of iJailbreak. Talk about hackers/developers but yeah – they are the best! iPhone Devs have been keeping mum so far but hey, this method works the best!

Unlock option works with only 1.1.2 and 1.1.3 OTB iPhones and that makes sense cos’ we already have solutions for 1.0.2 and 1.1.1 iPhones. Activate and Jailbreak option works with any version of iPhones. So no more oktoprep->downgrade->upgrade stuff which saves us lot of time and better yet : a much more efficient solution!

Download this application from a fast download mirror. Happy unlocking!! Do comment if you have any issues with bootloader or baseband and use this application at your own risk!!
