Upgrade your Palm III/V/VII from Palm OS 3.0 up to Palm OS 3.5.3, featuring some fixes, enhanced security, and more. For the latest supported version, see Palm OS 4.1 Upgrade.
To determine your current OS version, navigate to Applications > Menu > "Info" > "Version". If less than available, use the appropriate PRC or installer below. A compatible version of Windows is required to perform installer updates. It is recommended to use Windows XP or older for best results.
Warning: these are only PRC update patches to be used within a single minor version of Palm OS (3.0, 3.1, or 3.5).
Updates 3.5.3 and 3.5.2 are only for devices running Palm OS 3.5.x.
Update 3.1.1 is only for devices running Palm OS 3.1.0.
Update 3.0.2 is only for devices running Palm OS 3.0.x.
Newer Palm Desktop suite (e.g. 4.1.4) already contains these updates and will install them automatically with the first synchronization.
