Hi BA.
It is IPhone 2G, updated to FW 2.1. It was simlocked to Orange (France) and would not work on SFR, my operator.
My son lent me an old Orange SIM card (no longer valid and impossible to phone with, but recongnized by iTunes), which allowed me to use the iPhone as a dumb PDA (= no phone or SMS services).
I used the QickPwn for FW 2.1 and it un-simlocked the phone (the SFR chip now allows phone and SMS services, though it says only Emergency Calls possible).
This means that I now have a phone, but no other function.
When I plug into iTunes, it says the SIM card does not come from an authorised operator.
I am using iTunes 8.0.0.35 and Vista Home Premium.
Does this help?
Cheers.
