Just found this neat freeware app on
www.pocketgear.com. It allows you to easily change the PPC's "wait" symbol, to one of a number of different ones. (From a waving American Flag to Homer Simpson, etc.)
The developer is the same guy who did Tweaks2k2, which is a really good registry tweaking program.
Here's the link:
