Palm Pre devices are supported by MediaMonkey 3.2+ via the iPhone plugin (the
Pre appears as an iPhone), provided that the Pre is updated to the latest firmware.
If your Palm (e.g. Treo) is recognized as a USB Mass Storage device (i.e. it has
a drive letter when you plug it into your PC), then just plug it in and
follow the configuration directions for USB Mass Storage devices in
the MediaMonkey online help.
If your Palm isn't recognized as a USB Mass Storage device, then
you'll need to first install an application such as Card Reader
to your Palm, to enable it to appear as a USB Mass Storage device.
