I bought an iPhone May 29th as a graduation gift because I didn't believe the rumors (how stupid am I...) The day the 3G iPhone was announced I went to return my iPhone to wait for the 3G. I didn't do the "free upgrade if bought after May 27th" because my AT&T store said it was a rumor. I recently received a letter from AT&T saying that 3 out of the 4 lines on my family plan are eligible for upgrade, mine is not one of them. However, this was printed when I still had my iPhone. Does me returning my iPhone make me eligible, or am I still not?
