I found this out yesterday. I got my 2nd iPhone bill and it was over $400. I have the $99 plan that gives me 1,350 anytime minutes, nights and weekends free, free mobile to mobile, unlimited data, and 200 SMS. Well I went almost 800 minutes over my anytime minutes. So I called AT&T and asked if there is a higher minute plan that I can get with the iPhone. The women tells me I can get 2,000 anytime minutes and everything the 1,350 plan has for $20 more for a total of $120. She also took off about $235 off my bill cause I did not know they had this plan. Hope this helps someone out. Thought I would pass the word along.
