Hi guys

I was running a 2G iPhone 8GB on 2.2.1 via Quickpwn for windows. Was all nice, and I recently moved to O2 (iPhone carrier) in the UK on a SIM only deal (not an iPhone tarriff).

I got some advice that it would be OK to updade to 3.0 in iTunes, so I did. I now have the "unsupported SIM" message in iTunes, and the USB graphic on the phone. I know - I should have done better research - flame me.

Anyone know what my pathway back to 2.2.1 is, or the activation for 3.0?

I have iTunes 8.2 currently, but have found the old iTunes archives, and all the old iPhone firmwares.

I tried:
1. DFU mode and a Shift+Restore in iTunes but get Error 20.
2. Quickpwn 222-5 but it doesn't like the 3.0 FW. Refuses to restore an ealier FW.

Wait for off Pwn release. Should be very soon....

Try my method it works..

Many thanks for the help. I had trouble getting Quickpwn to put the phone into DFU mode, but was able to help it along manually.

Once that was done, all is back to normal.

Thanks again.
