• Joey Gibson's Introduction to Pocket Smalltalk

Of the two PST tutorials, this one is longer and more comprehensive. It provides an overview of the PST environment, building applications, using the Palm OS Emulator and the PST Debugger. If you're new to Smalltalk or new to programming the Palm OS, this tutorial is for you.

• Andrew Brault's Pocket Smalltalk Tutorial

This is the original tutorial for Pocket Smalltalk. It's short and can get you started fast.
It presupposes that you have a bit of experience programming on a Windows platform machine and a superficial knowledge of Smalltalk.
