The usual route of info leak with this one, that of delving into FCC files and as we already know the Sony Ericsson XPERIA X10 user manual has already hit the net waves thanks to the FCC, but now there is more discovered by the guys over at the BGR.

Apparently they were looking through the FCC PDF and discovered that on page 3, the Declaration of FCC Conformity, and found that is shows 3G bands 1, 4 and 8.

Now to the mobile phone knowledgeable person they would instant recognise this as T-Mobile’s AWS 3G bands, which means that it is quite possible that the Sony Ericsson XPERIA X10 is headed T-Mobile way.

So for the T-Mobile faithful here’s what to expect with the Sony Ericsson XPERIA X10 smartphone, a 4 inch capacitive touch screen with scratch resistant surface, 8 megapixel camera with auto-focus, touch focus, geo-tagging and LED flash, Android 1.6 OS, WiFi, Bluetooth, 1GB internal storage, microSD expansion up to 16GB and a 3.5mm jack.
