Any ideas on why?
I don't think that's true.
I know for a factAT&T has many different data plans for many different phones/platforms... The iPhone, for sure, has a separate data plan which is required to iPhone data. PDAs have a different data plan, as do the Blackberries.
Their voice service will work regardless of the equipment, but data does not.
You could always call / visit AT&T for confirmation.
