I have my iPhone 5 jailbroken, if I want to unlock it will I lose my jailbreak? Any suggestions on the best place to unlock it? I have AT&T and just changed carriers so I sold my phone on ebay but AT&T won't unlock until I pay off my contract (after they bill me for the contract termination) they said they won't be billing me until June 15th! They told me they can't take payment until I am billed. So now the buyer says he wants to buy the unlock.
