Not sure if this is the right section but:
I bought my iPhone 4 on release date and AT&T says I can upgrade again on 6/25/2011. I've upgraded every summer since 2007 so cool, same as usual for me.
Another phone on our line is 3G S bought late last year or earlier this year; well that one can't be upgraded until 8/31/2011. Before the 3GS purchase, it was the original iPhone from July 2007 (well over 2+ years).
So whats the reason that upgrade dates aren't the same regarding all iPhones?
