Please don't flame me, I've used the search and can't find an answer.
Whenever I update weather, or open an internet session using any of the available browsers, my TP2, of course, automatically opens a data connection.
When I close my internet session, the phone remains connected until I manually go into the Comm Manager and close the data connection.
Is there a cab available that automatically closes the data connection when an internet session closes ?
Thanks in advance for any help.
