www.wifi.aximsite.com for one of the best descriptions of how to do most things wireless with the Axims. However, don't confuse WiFi with wireless phone service. It's possible that T-Mobile is providing the trunk access and WiFi access point at Starbucks, but generally they are a cellphone carrier. Connecting via a cellphone is a whole new ballgame and would require you to have, typically, a Bluetooth card for your Axim in order to use your cellphone as a modem, of sorts. Higher end PDAs have BT built-in and still others have cell technology included, as well, making them able to access most forms of wireless communication (given you've paid for the appropriate service, of course).
