few things i found interesting.

The open source GPL that for all software include.

Private Browsing option - /etc/palmos/browser.conf
PrivateBrowsing=false

YahooContactSyncService, may show up later, I think it only handles email right now, but looks like contacts are on their way.

I also located both of the sqlite3 databases. One for the os itself, stores contacts, im convos, and pretty much anything that needs to be stored.

There is another that contains all carrier settings. not just for sprint, but for t-mobile and a whole slew of us and international carriers.

These are located in /usr/lib/luna

I just started looking, so we'll see what else i can find.
