I dropped my iPhone 3G today and the touchscreen is completely unresponsive. The external buttons work and I've tried resetting my phone several times-- no luck. My yearlong warranty expired on the 7th. AT&T told me to call Apple about it and have them deal with it because of the warranty guidelines.. I've also had the screen cracked before, but I had it replaced by an unlocking company. Is there any way for them to know this?
