I am well aware of the fact the Nokias and Sony ericssons have having the USB 2.0 speeds from quite some time but this news is not so old for the Windows Mobile devices. The maximum speed the windows mobile devices could achive was just USB 1.1.
The HTC Diamond offers true USB 2.0 . I was able to transfer a 700MB movie, “Never Back Down” to my Diamond in less than 4mins!
