Anyone have experience? Is it possible? A friend of mine is headed to South Africa and Europe for the summer and would like to take along his iPhone.

We tried jailbreaking it last night, but no matter what we did, we were told that we had the wrong ipsw file. FWIW, I'm not really all that sure WHAT we were doing... I think the software we were using was attempting to set the firmware back to 3.1.2.
