Motorola

I have a v400 phone which was unlocked for T-Mobile service and can't download ring tones or wallpaper. My phone tells me (through T-Zones) that although I may have that capability on my device, my phone is not supported. I don't know how to download from Motorola's website either because it doesn't recognize my phone as a T-Mobile serviced phone. Any ideas on how I can get these extras? I've already had to enter all the information to get t-zones myself - what a pain this has been.

Thanks in advance!
