Are there any cell phone plans out there where you can pay with Bitcoins?
If not, would anyone be interested in such a plan?
All anonymous, you buy the phone yourself then get turned on to the cell phone plan paying with Bitcoins.
For Prepaid wireless:
Tangible Cryptography / CellCoin
(Prepaid and real-time reload (RTR) )
And coming someday, BitcoinWireless
Tangible's will be for post-paid (subscription) plans when they start offering bill payment capability.
