Motorola RAZR V3i / V3t / V3e / V3r

Hi, I own a razr v3i and use it with tmobile. Anyway, I went to a tmobile store a couple days ago and noticed that they had a similar phone called the razr v3t. I looked at all the features and they're all pretty much the same except it has all those tmobile stuff like tzones and what not. I asked a tmobile rep which phones right now has video playback for caller ID and he said that the v3t has it(though he wasn't sure how to do it). I showed him my phone and he still didn't know how to do it. So, does anyone know how to do it? If you even CAN do it? Thanks in advance.

I had a samsung t809 before I bought this phone and that's one of the features that I missed the most.
