iPhone 2.0 beta 4 (5A258f) has released for few days. Unlike previous beta, it seems iPhone Dev Team will not release tools to support this new beta for unlock and jailbreaking. 5A258f requires the program to be run with signed code which means it is harder to run the unlock programs. iPhone Dev Team suggests users to wait for the final 2.0 which will be available in late June.

ZiPhone’s developer, Zibri, seems found his own way to “hack” his iPhone 2.0 beta 4. Take a look of the picture above, you can see that he is running the latest beta. He wrote, “The ‘hacking’ work has been done already”, and tell us we do not need to worry about the iPhone 2.0 thing. It will be okay.

Although he seems not releasing the tool (and there seems no leak of the latest beta on the internet.), it is a very encouraging news.
