AirSet + Verizon phones via wireless: the cost

Synchonizing the AirSet calendar service wirelessly to a Verizon phone? AirSet's Web site currently says: "AirSet Mobile is a subscription service, available through Verizon at a price of $6.49 per month. Airtime charges are incurred only while synchronizing, which typically takes 30 seconds or so, resulting in 1 minute of airtime utilization." You can also sync to AirSet via your phone's cradle and avoid those charges.
