Hi guys, who out there is using a Dell x50v?

I bringing mine up to speed at the momemnt and would be interested in swapping/sharing experiences. First issue I have to deal with is key mapping to CCF. It seems different to my old IPAQ. I have vol +/- and ch +/- mapped to the four function keys at the bottem, but only two of them seem to be working. I remeber some stuff about this a while back, but I can't find it.

Any ideas?
