I had Ringo on my Treo 180g. Just bought a Treo 600 and want to install the upgraded version of Ringo.

Question is, can I use the ringtone package I had purchased separately for my 180g? The 180 does not have a polyphonic ringer like the 600.

Are the ringtones different for phones like the 600 or do I have to buy a new ringtone package?
