My cousin had lost his iPhone a month ago when we were drunk at my house and I found it today. He said I could keep it, I know it's disabled so it's basically useless but his phone number is still on the phone. I'm scared Verizon will track it down and say it was stolen, which it wasn't. I've got it set to Airplane mode with just the WiFi on. I just jailbroke it. Is there anyway I can remove his number or possibly block/remove the Verizon network association all together so that it is just an iPod using something from Cydia or any kind of method? Also, will me downloading apps, signing into Facebook, and other things with my personal info, sent to Verizon so that they can track me using that?
