Try reregistering your BlackBerry. I would just pop the battery out and back in and see if that helps (when it reinitializes). THe browser is pushed down by your carrier.
No, i mean that i am using the application loader with Desktop Manager to push version 4.0 onto the unit. In the list of applications to be installed there is a 'browser' option with a list of sub obtions below it (Such as TLS support)
I hit the 'remove' button by accident and have not been able to get it to come back.
