How do you do a register now on this device ? I need to send a wireless registration message to the network.

Wow.
Something I actually know the answer to....
On your phone go to "Blackberry" then "Setup" then "Host Routing Table" move the cursor to the listing in bold print, press "Options" then select "Register Now" and hit ok.
Done.
You will get a text saying you have registered with the network almost immediately.

Now, if I could just figure out how to make the BB Browser work with T-Mobile USA.....WAP works but no joy the BB....
