New T-mobile Visual Voicemail - Cab Install
From The New Leaked Rom
At the moment vvm is only for blackberry 9700 and android devices. when you log into your mytmobile.com account just change the pic of ur device to a blackberry 9700 device and when you go to change services it will let you add the vvm soc for free. then you can switch the device back to your TP2. it goes thru instantly as if you called in to make the change. i just did it and it worked.
Have Fun!
