First, I don't see anything in my post about AT&T or the iPhone.
Secondly, you would propose that customers could make any plan with a cell carrier they want? How would the cell carrier do business with every customer making their own plan.
Why would anyone want an iPhone without a data plan? Using data is half the purpose of the device.
Sorry you are so anti AT&T and feel it's a monopoly. Perhaps you should contact your congresspersons and ask them to look into this.
