"Congrats on finally making it happen! An easy-to-use PIM for Windows Mobile that still holds flexibility enough to make most users have it their personal way. Most of all I like the minimalistic clean user interface that I am missing from my Palm OS days. This PIM is what actually should be shipped within the OS itself."  -Jörgen

Agenda One Update / Upgrade Policy
When purchasing a license for Agenda One, you will receive an ID and Registration Code that will be valid for all of the updates within a major series of the product.

For example, if you purchase Agenda One when the current version is at 1.2, your registration code will be valid for all of the Version 1.x updates. (i.e. Version 1.5, 1.9)

There is no guarantee as to the number of (minor version) updates that will occur in any major version of the product.  New major version updates are planned to occur approximately every 6 to 12 months, and/or when updates to the Windows Mobile operating system demand product revisions for compatibility.

Your continued feedback helps us understand what features you need.  We welcome all of your comments and continually review all of your suggestions for inclusion in future product updates.

How to apply updates to Agenda One
You may update Agenda One directly from your device by going to the "About" screen and selecting Menu > Check for updates
If the newest update is a major version higher than the installed version (i.e. you have Version 1.5 installed, and Version 2.0 is available), you will be prompted before installing that this new version may require the purchase of an upgrade.
