ok got it working after a 20min call to tech support.
data provisioning by default is under start->settings->system-> "Update profile"
however, this was not working for me because it had the wrong info but would not update
i had to enter ##3282#, put in my MSL code, click on "edit". then "menu" then "restore" which cleared out all the info and soft reset the phone
then, after doing that, do the regular "update profile" and everything was working after that!
my speed test is only showing 600 kbps though, which sucks because my treo/mogul constantly get 800-900
