Two Snapdragon-powered phones with large touchscreens are taking the first steps to the pockets of T-Mobile US consumers. Yep, the Sony Ericsson XPERIA X10 passed through FCC testing and it and the HTC HD2 both are on their way to T-Mobile USA.

The Sony Ericsson XPERIA X10 has obviously passed through the scrutiny of the Federal commission, but the interesting part is the 3G test. The tested UMTS bands were I, IV and VIII, or in other words 900/1700/2100MHz. That definitely points in T-Mobile’s direction.

WMExperts bring the second bit of good news for T-Mobile customers – they got the ROM image for the US HTC HD2 and it seems heavily bound for T-Mobile as well. They also share some of the versions of the apps that will be available inside – ROM version 2.01, Windows Mobile 6.5 build 21896, Opera Mobile 9.7, TeleNav GPS navigation 5.5.34 and Teeter 2.0 (hooray!).

The rumored release date for the HTC HD2 in the US is March 2010. The release date for the Sony Ericsson XPERIA X10 on the other hand is anyone’s guess.
