All the ChoiceWay Guides for Palm OS have been upgraded to version 4.01 for compatibility with the new Palm OS ver 5.0. (Click here to see a list of Palm OS 5 devices.) There was also a minor content update to all the Palm guides in ver 4.01.
Unfortunately, it was not possible to make the new version 4.01 ChoiceWay Guides compatible with older devices using Palm OS ver 3.5 or older OS versions. If you have an older device such as Palm Vx, you should not use ver 4.01 of the ChoiceWay Guides. If you attempt to use a ver 4.01 guide, you will see a warning notice, when you start the program. Most Palm OS devices, can be upgraded to Palm OS 4.0 or 4.1. Contact the manufacturer of your PDA, if you want to upgrade your device.

The following compatibility matrix shows which version of the ChoiceWay guide you should use depending on the Palm OS. If your Palm device uses OS 4.0 or 4.1, you can install the newest 4.01 guide version, but you should delete the older guide first.
