That's unfortunate.

BitcoinWireless has not yet launched either.  That least BTCBuy as the sole remaining source.  Each month I refill my mobile phone service (currently Virgin Wireless prepaid, previously T-Mobile prepaid) and use either CellCoin or BTCBuy and have had great experiences with both.
