Last month, I activated my Iphone with a Blackberry Data Plan for $30month. Only got a few of the annoying Text Messages from ATT. Yesterday was the end of my first month. I went online to check my bill. First, (not surprisingly) it lists my device as Iphone. But, it correctly lists my plan as the unlimited Blackberry. However, it lists my balance due as $116.80 for the first month! It is frustrating, because it says "billing details" will not be viewable for 10 days. I used no voice, other than one accidental 1 min call. Any ideas???
