I'm just trying to find out how Apple will handle these things if the phone is presented to them locked with the activation screen on it? That is, without any evidence of unlocking at all, just a description of the problem and the customer's statement that there is what appears to be a hardware problem and that they restored the phone to the original factory settings before coming to the apple store, but did not re-activate it. I fully understand what you're saying, and that if unlocked and the unlocking has caused a problem, the customer will be responsible for repairs. But Apple hardware fails too and it may not be at all related to the software unlock.
I have ATT myself, but the old pre-cingular ATT. MY plan is great and I don't want to get a lesser plan just to be 'legit' with the iphone. And, as I understand it, I can't add the iphone data plan to this old service.
