Motorola V300 tri band or quad band?

I just bought an unlocked motorola v300 camera phone from ebay. The seller said it was a quad band which I wanted, as I travel and want it to be operational worldwide. However, I noticed on the box and the manual that it lists only 900/1800/1900 -- which appears to me like a tri band (850 missing). If I understand correctly, I will have limited connectivity in the Americas. Can anyone confirm if the V300 is a quad band or tri band, and any issues they've had with this phone?

Thanks!

Thanks. I am actually on AT&T/Cingular. Not sure where I need 850 though --would this include places in the US?
