Re: I unknowingly bought a lost iPad via Craig's List. What can I do to activate it?
Apple added the Activation Lock to iOS 7 to combat the rampant unauthorized reselling of lost/stolen devices. There is no way around this lockout… your only options are to contact the person you bought it from and get (1) the Apple ID login credentials, or (2) your money back. If you bought it from an honest/legitimate seller, they’ll help you out. If you bought a stolen device from a scumbag, you are simply SOL, and you now own a pretty, albeit expensive, paperweight.
