Encryption for a PDA

I'm looking for an encryption program to use on PDAs. The program must be easy to use and have at least some automation. What would you recommend?

What application? Encryption for e-mail, general encryption for data, VPN/SSL or all? In other words, what are the business requirements, and what is the risk you want to mitigate?

I've liked F-secure products. They don't have crypto for what I have (a Palm Computer), but they do for Pocket PC.

If you are interested in just a secure store for sensitive info, there are shareware products (search on I use Secret! for that.

There is a version of PGP for PalmOS, but it does not look automated.
