Hello. I'm a long time lurker but I rarely post, but this has got me perplexed. I purchased an iPhone 5 off of eBay that had iOS 6.1 and was jailbroken. It was also unlocked (the seller was using it on Straight Talk) but it is a Sprint phone. (I removed the iPhone 5 nano app to try to activate it on Sprint). The "Problem" is that the IMEI number on the back of the phone and the IMEI number in the About section in the settings do not match. They are different numbers. I asked the seller about it and he states that the back was replaced because of scratches. Does this sound feasible to you? Is it possible the IMEI number could have been changed?
