My phone has started running in to hardware problems, a dead line of touch and regular reminder that 'this accessory is not compatible with iphone' despite there being no accessory connected.

I attempted the sensitivity fix for the dead line but it didn't help.

I plan on making a visit to the Genius Bar tomorrow, should I just restore my phone to 1.1.4 and take it to them in a useless state? Will they even service my phone without an AT&T contract?

Any advice would be appreciated. I would hate to take my iPhone back to Canada in it's current state. Thanks.
