The Treo 700wx has been proven to work well with OggSync. You can install it by pointing the treo browser to http://oggsync.com and clicking on the OTA install links for .NET CF 2.0 and OggSync itself ( <- Over there on the left pane). This phone was tested in house during the initial development of OggSync and has been used by OggSync users since October of 2006.     Â
