I have a 3G that was bought in America while on a long holiday and brought it back to Doha, together with a Turbo SIM. It was running v2.1 and quite happy - I have an AT&T SIM too, but obviously won't work outside the US.
Now, foolishly I ugraded to v2.2 last night and the thing won't work anymore with the Turbo SIM. Being an old duffer and not that computer savvy I have just found this group... damn wish I knew then what I know now!
Anyway - is it possible to remove v2.2 and go back to v2.1 and reverse the baseband changes? I did search the threads here and I downloaded Pwnage and the v2.1 firmware as mentioned in another thread but when I connect the iPhone to the Pwnage programme it tells me that the Firmware isn't supported in my phone...
Do I now own an expensive iPod Touch?
