After we had the video demo of this spectacular smartphone, we notice that the registration page had taken out the February 10th launch. Now in its place is this: "Pre-Register - Expected launch: To be announced". That's not good, but at least we get more insight on SE's plans to bring this phone to the "Americas".
According to the Sony Ericsson XPERIA X10 page, there will be an American version of the XPERIA X10. Apparently, this version will work with bands that fit both, AT&T and T-Mobile, and you can see that on the quote below:
But then, it shows no love for the necessary 1700 band that T-Mobile needs, in order to get 3G, as you can see on the next quote:
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.
Now don't get too excited if you have AT&T and want to get this Android phone, remember that SE is saying the Americas. So for all we know, this XPERIA X10 might be getting ready to land up north in Canada, or down south in Mexico, and not necessarily in the good old US of A.
