Well I don't see how the charging pod will sync with your PC since the pod connects to the positive and negative terminals at the back of the BB where the battery latch is.
Look at the pics in this thread.
Not connecting to the microUSB port = no sync.

The BB site is known to have misleading info for the 8300 charging pod and I would bet the design is exactly the same which means it just charges it (they advertise there's 2-colour charging LED and will flash when receive messages, yadi yada...etc which is not true).
