Will ZU C6806 from Bell Mobility (Canada) work in the U.S.?

[chinee]

Looking to get a ZU, preferably the 6806 since I'm with AT&T, and I found one for sale from Canada, probably on their Bell Mobility network...

Does anyone know if this would this work here in the US?

Also, on a side note, anyone familiar with any issues purchasing from Canada via ebay... customs, duties, taxes, etc.?

Thanks in advance.
