Do you have a BlackBerry plan on your account? Have you tried doing an HRT reset and a Send Service Books? For the HRT Reset, go to the Options Wrench, then Device, then Advanced, then Host Routing, then press the BB (or Menu) button and select Register Now. Follow this with a Send Service Books, go to the Email Setup icon, sign on to your account, then press the BB button, select Service Books, then Send Service Books. Finally reboot your device.
