I was wondering if you can use the iPhone with a regular family plan rates? For example a regular family plan with three phones and only one is the iphone? So then i'd pay the normal$9.99 to add the iphone line and 15 for 1500 texts and 30 bucks for data. Or does AT&T not let you add the iphone to a normal family plan? Also, if I had all iphones, would they automatically switch me over to the more expensive iphone family plan?
