So the proof that the Constitution is unambiguous is that you need to read some other documents in order to understand it?

You need to call Cingular. Assuming you don't have a PDA (aka a Blackberry, Treo or something like the Nokia E62) you can get the SmartPhone Connect Unlimited plan for $19.99 a month. Or, if you also want text messaging, you can get the MEdia Max 200 plan which is unlimited data plus 200 text messages for $19.99. If you do have a PDA, you can get an unlimited Blackberry Connect plan for $39.99. The 5mb plans only cost $9.99 these days.
