we were able to get VVM to load on the phone, by modifying the alx file and adding at&t's vendor ID to the list. it allowed the actual app to load and then we set it up. i had to call at&t and tell them it was a 9800 (which was VVM enabled on at&t) so the account was provisioned properly. upon testing, the first VVM would come through properly and notification was made. but if you called yourself and left a subsequent message, it was never delivered and VVM "broke" after that. we all gave up on it after awhile. someone made a VVM OTA download back in the day which allowed you do manually load the VVM app. or you can go into the vvm alx file in the OS and edit yourself with t-mobiles vendor ID to get it to load. but then again, if its blocked by t-mobiles service books, or there isnt one for it, the app still may not show on the screen even if its installed on the device.
