This is from the US part of the page:

It has 3G, as do all higher Walkman phones (mine is 850i). It does not have Edge, for example, or HSCSD but has WLAN.
The W960 operates in GSM 900/1800/1900MHz, & UMTS 2100MHz

Seeing how Cingular uses UMTS in 1900 here in the US and there is no 850 band on the phone (Cingular also uses that) the W960i would be a crippled phone in the US market. 

No 3G and only one band to operate in.
Maybe if they came out with something like say a W960A (a for americas)
