HTC HD2 and Sony Xperia X10 surely took their own sweet time for the red carpet welcome by T-Mobile USA. Well they didn't quite make it in time for Christmas, but spring is not far away for these Snapdragon featuring monsters.

Xperia X10 has passed the FCC testing for EDGE 850/1900 Mhz frequencies, T-Mobile compatible WCDMA Band IV, Wi-Fi & Bluetooth.  Jointly with HTC HD2, it will take it first steps towards stardom, probably around March 2010.

Wait and watch in anticipation for the battle between Windows Mobile 6.5 and Android 1.6.
