Help activating/unlocking please?! Stuck on emergency call screen
Hi I'm wondering if anyone can help me or possibly tell me what is best to do next. I'm new to unlocking/jail breaking and not particularly tech savvy.
I've recently got a used iphone 3Gs which I was told was locked to the Orange network here in UK. I got a sim from them, popped it in for activation but iTunes tells me the sim card is not supported and I'm stuck on the emergency call screen. Apple has confirmed that the phone was in fact registered with Orange but was swapped for a new phone previously due to damage, and the carrier provider may have forgotten to update/re-register the current IMEI number in their database. So I went back to Orange with this information but they have told me that it's not possible. Tried putting in other sims but still the same response from itunes.
Pretty much at my wits end now and clueless. :confused: Should I consider jailbreaking/unlocking and is it possible to do so? I have no idea what iOS and baseband it is currently on. :( Help and suggestions much appreciated! Thank you!!
