Fix Blackberry Address Book Syncing with BES Issues [Tips]

I had a client today where certain contacts that were in Outlook were not showing up on his Blackberry. I tried resending the Service Book from the Blackberry Manager software on the BES Server, but that did not fix the problem. Then I tried to activate the phone, but the address book would fail to synchronize. I did not want to wipe and then activate the phone. That is when I found this gem of a tip:

On the Blackberry device go to Options->Advanced Options->Service Book
Find the service: Desktop [SYNC] and press down on the option key (sometimes called Blackberry key) and select Delete
Stay within the Service Book screen and now press the option key again and select Undelete
Wait about 2 minutes and then check the address book for the missing contacts.
