We had ‘some’ trouble unlocking our French iPhone before we could use it on a foreign network due to a software bug in the iPhone 1.1.2 firmware as you could read in one of the previous posts. The end result was a very expensive iPhone which we still needed to jailbreak, kinda stupid and a waste of money. Yesterday Steve introduced the 1.1.3 firmware as expected so Jelle took the dive and tried it out. Well, I'm happy to report it works perfectly!
I synced my iPhone and choose to upgrade. I didn't switch my SIM card back the the Orange one so I upgraded with my Base (a Belgian operator) SIM card. iTunes downloaded the 1.1.3 firmware and upgraded my phone. I got an error saying my SIM was locked, locked as in PIN locked, not network locked so that's fine. I entered my PIN code and docked my phone again. There it is my legally unlocked - non jailbraked - iPhone!
