Razr V3 Wallpapers

I just got a black Razr V3 phone, I have a USB cable that fits it, and I want to add my own wallapapers and stuff to it, but I don't know what kind of software I need, or what... I tried a "final version" of Motorola Mobile Phone Tools, but that didn't really seem to work... Any help would be much appreciated. Also, what resoulution and format to wallpapers need to be for this phone?

USB cable is the really shit way to do it. Get a bluetooth dongle.

If you want to use USB, then Moto Phone Tools is the only way.
