There was a document in the zip file, but it does not load onto my T3 as I don't have a sim card. Don't know if that will help with any of the explanations.

As far as the differences between versions go, I think they have mainly been bug fixes, so a higher version should work better on your palm

<addition> and there should be no problem in installing a newer version over an existing game (or at least that is what Arthur has been saying)
