I would like to use syncML as an component to make an calendaring, schedule, adressbook, call.logging for an advertising agency but the phones must use syncML. The first app to use syncML will be iSync and iCal on the mac. There are several 6310i phones in use and we would like to use those or suplement with others. Probably not the 7650 but smaller and cheaper. Bluetooth and syncML is essentail it seems.
