Considering switching from AT&T to Verizon for all your iPhone needs? AT&T would really prefer you don't. That's why they're giving 1000 free minutes to all their iPhone customers.
You may have already gotten a text message from AT&T telling you as such. If you didn't, simply text "yes" to 11113020 and you'll get em. Not that most of us need any more minutes; who talks on the phone these days? AT&T, if you really want to get in my good graces, a free gig of data would do the trick.
