X10-3The guys at Android Fans spotted the following specs from the official Xperia X10 site:

Networks
GSM/GPRS/EDGE 850/900/1800/1900
UMTS/HSPA 800/850/900/1700/1900/2100

The specs show compatibility with both AT&T and T-Mobile but the following line nixes T-Mobile as it explicitly takes out the necessary 1700 band T-Mobile needs for 3G:
UMTS HSPA 800/850/1900 only available for phones sold in Americas (except Brazil) and Australia. UMTS HSPA 900/1700 not available for phones sold in Americas. UMTS HSPA 1900/2100 available worldwide.

So, can we say Xperia X10 will be available in US through At&T?
