I found that on the tech specs page, the phone is listed as supporting these frequency bands:

UMTS Band 1/4/8 (2100/AWS/900)
HSDPA 7.2Mbps

Since I'm actually planning to get someone to help me get one from the US and ship it over here in Australia, does the Nexus One actually support all 3 UMTS bands? Or does Google ship out different models depending on which location you are ordering from?

I do need a phone that operations in the UMTS band I. So I am kind of hoping that it does supports 1/4/8 instead of just a single band dependent on location. Thanks for any advice!
