But, be aware: the process is not as simple as ZiPhone… Be careful!

And, I have only tested it on my 1st gen iPhone. Haven’t received my 3G iPhone yet !

Basically, the principle of the Pwnage tool is quite easy:

1. You “PWN” your iPhone running system 1.1.4: this operation alters the phone’s bootloader and “breaks” the check of signed software. After this operation, the phone will let you install any unsigned ipsw file via iTunes.

2. You create a custom 2.0 system file that will activate, jailbreak (=make the system read/write) and unlock the baseband (allowing it to run on any GSM carrier).

3. You put your phone in recovery mode, and restore the custom IPSW file directly from iTunes

4. Once it’s done, the phone unlocks itself and here we go!

So far, everything worked fine on mine, including AppStore!

You can download all the stuff needed (for Mac…) here: Pwnage 2

A full tutorial (with screenshots) will follow soon!
