Call me stupid, call me naive, but I bought a used Iphone off of Kijiji. (Montreal) Now the guy said it was bought from FIDO. So now I bought a SIM card from Rogers to see if it would work even though the guy said it was a FIDO phone. It said "Invalid SIM card." At this point, i'm just hoping it's not a stolen/lost iphone.
So now what do I do now? Do I have no choice but to get the phone jailbroken by a third party? What are my options here? I'm not very knowledgeable when it comes to this stuff. I apologize if there's a really simple solution, hehe.
