As a thank you for not jumping ship, AT&T is offering existing iPhone customers 1,000 free rollover minutes. All you have to do to get them is text, “YES”, to 11113020 by March 31st, 2011. It should also be noted that by sending this text, you’re opting in to receive future offers. But hey, it’s 1,000 free minutes, and you can always opt out again later.
