Classic will still run the apps that are not Certified, but Classic Certified apps will feature the logo now telling you that developer of a particular app tried it and can confirm it works well with Classic.
As a user, all you have to do is look for the logo.
The Classic Certified Logo serves as a seal of approval letting you know that you can use the Classic Certified application with confidence.
(And if your favorite app does not feature the logo, feel free to forward this post to its developer.)
If you are a Palm OS developer, and would like to distribute your application for Classic on Pre, now you can manage the whole process on your own and have your Classic Certified installation files ready in just a few minutes (and for free).
All you need to do is:
1. Create your account with MotionApps (form available here)
2. Test and confirm if the application is working well with Classic
3. Upload it for signing and then download signed file ready for distribution
More details are available on our website within Developers section including helpful documentation (compatibility guide, test cases and marketing materials) within Classic Certification Kit.
