Might want to check this thread where we discussed this a few months ago.

After getting my Tungsten C, I've found that I want nice looking icons so I use AppIcon to modify non-color icons to hi-res ones. If you care enough, I can post the process used to make icons and transfer them to the Palm. I also use the Today app you mentioned, with the PalmOS 5 Hi-Res skin by the author. A few other apps are Filez, Calcul-8, and Converter (conversion between anything). I've found a few more games that I like: Marbles^2, Pilotski, Vexed, Tangle, Exodus. These can all be found on PalmGear or FreewarePalm.
