Data Plan: how does pricing work?
I returned my defective iphone 4 to AT&T yesterday, and after repeated assurances from AT&T that when I purchase a replacement iPhone 4 at the Apple store (which I did 30 minutes later) that my contract remained unchanged and that I'd still have my grandfathered unlimited data, I found that I only had the new 2gb option. The AT&T manager is going to "submit a ticket" to try to get this changed, but I may be SOL. I'll have more to say on this in a separate post about my unfortunate return experience.
Anyway, I've been going over 2gb for the last 3 months: I like to stream radio and podcasts. If I go over the 2gb cap on say, day 25 of the month, and I choose to buy more data, do I pay an additional $45, or do I pay the difference of $20? (I was thinking that $45 was for something like 5gb or unlimited, maybe, I can't remember).
