Had my 3G since it came out and it's always had a case around it so the phone looks brand new. Last night I dropped it on the sidewalk and it hit pretty hard but thanks to the case nothing besides the case was scratched or visibly broken. However, I noticed today that the 'E' key doesn't work on the keyboard. Actually, that little section of the touch screen is very flaky so something broke. I did a full restore and it didn't fix the problem. Will AT&T or Apple take it back and give me a new or refurb phone if it doesn't look physically damaged?
