incal: one other thing to check for on your handheld device are the "APN settings", usually found in {Settings -->} Options --> Advanced Options --> TCP. You may need three pieces of information - the Gateway IP/hostname, the username, and the password. Check out:

The settings vary from one cell provider to the next. You also may or may not need to add a parameter to the very end of your URL:
;deviceside=true
Check the description of the javax.microedition.io.Connector in the RIM API documentation.
