You must have bought your phone about the same time I bought mine. It comes with 1.1.2. I downgraded to 1.1.1 but can't jailbreak it. Most of the time the browser hangs when trying to install AppSnapp or when it does and returns to the Activate Screen it never actually lets me into Springboard.

I'd be interested in knowing which set of instructions you followed to get this far.
All I want to do is run it on O2 PAYG.
