I have an iphone 4 8gb. I brought it on Ebay and the buyer is legit (they told me it was their , not stolen). that was back in august. So i factory unlock it so i can use overseas. It worked for a while, i even used the unlock and jailbroken phone in the US. but something happenned (the itunes connect came out) i gave it to someone there but i have no idea what they have done to it. Now the phone can no longer be restored. One repair person when i came back to the us told me there is no imei or whoever i gave it to was trying to change the imei and it can no longer work on any network.so the phone is useless. Should i send it to Apple? i tried contacting the owner but no answers and ebay rules states after 90 i can't contact the seller on an item. Anybody has a suggestion or is the phone toast?
