AFAIK, to qualify for this special thing AT&T is doing, you need to meet both of the following requirements:
1. have been an iPhone 3G "early adopter" (i.e. bought in Jul/Aug/Sep last year)
2. have a monthly bill of $99+/month
Which is retarded. They are once again going out of their way to divide their customer base. Either make it available for everyone; or no one. Another wonderful PR debacle they have gotten themselves into. I hope this gets as much press as their lack of availability of MMS/Tethering at launch...
Glad I got mine contract free...I'm headed to T-mobile.
