Once you have this info and see the Identity string you can remove with this command:

Remove-ActiveSyncDevice -Identity ‘Domain.corp/Users/ExchangeActiveSyncDevices/iPhone┬žApplC4YF6T8DFFD9’

**Please use are your own risk!  This should delete the partnership. You can do this through the Exchange Management GUI but I ran into an issue where that was failing.  If the persons name is changed or the Organizational Unit he is in changes.. the GUI may get confused and not apply the proper Identity string.  Using this command you should be able to find it.
