Nope! His contacts will not be lost. My wife uses the same service he does, which is the "BIS" - or "BlackBerry Internet Service". This is one normal consumers typically use.

Using BlackBerry Desktop Manager, you can back your contacts up... which is super important to do in case you lose or damage your phone.
