I was wondering. Since the new iPhone came out the old iPhone (very slowly) will be dropping in price. if i bought one used on ebay would i be able to update it to 2.0 and use it (without jailbreaking) without a plan? I have no need for the phone part of it. i just want to useit as an iPod touch with a camera and speakers. is there any way that would work? Also if it came down to it and i had to jailbreak it. is there anyway i could put it on my sprint network? Because i know sprint doesnt use sim cards is there any possible way i could pt it on sprint?
