I'd say if everything is working fine for you, don't worry about it. If you run into problems, such as sync'ing to Outlook with Desktop Manager, post the particular problem and details if you can't solve it yourself. (FYI searching on exact error message text almost always leads to the answer, maybe not always a solution, but an answer.) Posted via BlackBerryForums.com Mobile
