I recently purchased an iPhone 4S from Craigslist that had been reset when I bought it. When I try to activate the phone with the Apple ID that the previous owner gave me I receive an error saying that the account provided couldn't be used to unlock the device.
I know that it needs to be associated with the correct account but how do I even tell what account the phone was activated with originally?
The only thing I can see on the activate phone screen is the following:
This iPhoneis currently linked to an Apple ID (firstname.lastname@example.org). Sign in with the Apple ID that was used to set up this iPhone.
Is there a way to show or reveal the Apple ID that is associated with the account? At the very least I want to contact the original owner to see if it was stolen from them but I can't even do that. Very frustrating.
