RIM does not want this but has no choice. They are paying royalty fee based on how many people uses DM to sync using third party sync tool. All the process does is it records your pin number.
There used to be work around by changing registry key in earlier versions of DM (prior to 5.0) but was changed in 5.0 and can't work as it used to before that.
Workaround use older version of DM 4.7 and older and change registry key.
