Activating with stranger's SIM?
I bought an iPhone 3GS on eBay, it was jsut supposed to be the iPhone but it came with the seller's AT&T sim. I re-jailbroke it to get it to 3.1.2 but hacktivated it (I didn't realise i had the AT&T sim). Now I have it hacktivated and jailbroken etc and it's working perfectly except for push!
I was wondering is there anyway I can use this guy's sim to activate my phone? I don't have any information and I don't know what's needed for activation? If it's possible, is there anyway to return to the activation process without restoring everything?
Thanks if you read this far, I'm hoping for an answer :)
