Hi,

After upgrading ActiveSync 3.5 to ActiveSync 3.6 on a MS Windows XP
operated system, I cannot sync my IPAQ 3660 nor my HP Jornada 720
anymore. Synchronization works fine with an IPAQ 3850.
After downgrading to ActiveSync 3.5 I am able to synchronize data
again successfully.

Guess not all devices are supported by ActiveSync 3.6 anymore......
