I went to test out adding my company's Exchange email account on my husbind's iPhone. I went through the paces and at one point the screen shows me that my Address Book is about to replaced by the Exchange AB once I finalize the setup. I cancelled the setup. How can this be?! That's crazy. The whoe idea is that I can have several different email accounts, Mac.com (mobileme), Exchange, Yahoo, etc.

Has anyone else experienced this AB replacement? I don't want to lose my Mac.com or Yahoo address book entries just by adding an Exchange account.
