OK, I unlocked my iphone through unlock fusion and since they are selling at great prices on ebay decided to try and sell it unlocked and then rebuy it later.I sold it and I used the erase and reset all settings right before I shipped it out and it relocked the phone. I thought the lock was suppose to be permanent. Beware you phone could relock. I have contacted Unlock Fusion to see if he can re unlock. I'll post here what he says.
