When I downloaded my aim I got it from the UK FTP server. I've been using that version for about a year and have never had problems with it.
I've seen these listed in this thread and in others:
GSplayer - Plays Shoutcast streams and mp3's streamed over wifi from my server.
BetaPlayer - Plays Divx encoded videos...also plays streaming videos well.
MiniStumbler - Pocket version of Netstumbler...need I say more?
WiFiFoFum - Similar to Ministumbler...sometimes will pick up AP's that ministumbler doesn't (and vice versa.)
Microsoft Windows CE Terminal Services client - I thought this was supposed to come with WM2003 but mine didn't...and I can't find the link now that I downloaded it from. Recently I have been using the PCAnywhere Mobile client (although it's not free) that comes with PCANywhere 11.5, it's both faster and supports a 'zoom-to' feature that makes it easier to administer remote systems from a small screen. Makes me want the VGA screen of the X50v.
