While were at it, text messages work out to be something like a million dollars a gigabyte of transfer (at least in Australia I don't know if the US is still so backwards). Now you would think the marginal cost on each text message would be so small that they would just throw them in for free as a deal sweetener? Unless I don't know something about the costly way they are sent? I'm guessing it's just so much of a cash cow for carriers.
