Glad you got the gmail issue figured out and thanks for sharing it with us.

It's been a while since I reviewed the XV6900, but I seem to recall that it plays mobile youtube-- http://m.youtube.com . Very few phones can handle full Flash and desktop youtube-- some Nokia S60 phones, the HTC Touch Diamond being the ones that come to mind. There are hacks to enable full youtube playback on Windows Mobile phones that involve installing a few hacks and a modified version of the TCPMP video player.
