Hi, My Family and I recently switched to AT&T and I got the iPhone 3G. The guy at the store told me that I needed to pay an extra $30 a month for the "unlimited" data plan, which covered unlimited data on the internet. I agreed and got the phone. Yesterday, I tried to d-load, Tap Tap Revenge 2.6, and it says that since its over 10MB, I need to connect to Wi-Fi! What gives? I thought I was unlimited? Did they lie to me? Also is there a "limit" to how much web browsing or app downloading or e-mailing I do per month? Thanks for clearing this up for me!
