We've stated several times on here and in the newsletters that the Mark 1 remains fully supported. The source tree is common for both revisions, as the Mark 2 really isn't much different in terms of architecture.

Of course there will be Mark 2 specific features, such as voice recognition, which will not work on the Mark 1. Any new feature that is compatible with the Mark 1 hardware, such as WMA, will be available to everyone.

Regarding your sync problem, are you running version 10A of the software? Synchronisation is extremely reliable in this latest release.
