MacGod writes: Macworld is reporting that AT&T has announced three price plans specifically for the iPhone. In addition to selecting any of AT&T's regular price plans, iPhone customers can choose from three unlimited-data plans. The plans include 450, 900 and 1350 minutes for $60, $80 or $100 per month, respectively. In addition to the unlimited data, all plans include 200 SMS messages, unlimited mobile-to-mobile calling, and unused minutes roll-over to the next month. As expected, registration and plan selection is done through iTunes.
