PSA: it appears SyncBerry has fallen off the planet; the website is bunk and Handango has removed many links to buying the software (good thing I backed up the installer files I paid for!). I went looking for a newer version when I discovered this (they sent me a beta of an upcoming 4.2.0.0 release but I never heard from them again after that - that was 10 months ago).

It appears the only two players left are Nexthaus SyncJe and the Funambol client plugin (which hasn't been updated in a year and a half). Which really means the only player left in the game is Nexthaus SyncJe.
