My caveat has nothing to do with the warranty. It has to do with the $400 paperweight you'll have if things go wrong (easily done).
Personally, I urge you to try Obfuscate or ChangeMe, little apps that hide app icons on your home screens. Obfuscate is available for download in our
free downloads area (PalmOS > Treo Utilities). If you're starved for memory, move some apps to an SD card (DocsToGo can do this to itself) with PowerRun or a 3rd party launcher utility such as ZLauncher or LauncherX.
My 2¢.
