Ok so I see an app for Visual Voicemail installed on the 9800, but can I use it with T-Mobile's VVM service?

I've added the service to my T-Mobile account, but not sure what else needs to be done. What service books do I need, if any? What system edits need to be made to the default AT&T VVM setup?

I had VVM working on my 9700 and it started working automatically when I switched devices to the 9800. I did have to add the service books for BIS/Browser manually to the device. I'm not sure whether it worked before that or not as I didn't have a chance to test since I installed the service books right away after switching devices.

I've found that if you try and setup VVM on the device before having TMo activate it on your account that it can screw up the VVM app. You might need to uninstall VVM and reinstall it.
