I'm not sure if this is an iPhone 4 issue or an iOS 5 issue (I have the GM), but in my contacts list I have, naturally, my wife's contact info. Its never changed. But lately, when she calls, her name doesn't appear any more, just her number. When I call her, her name appears appears as usual, and in the Recent Calls list, her name will appear when I've called her. When she calls me, however, only her number appears in the Recent Calls list. Also, under her name it says 'mobile' when I call her, but the incoming call shows 'main'. I only have her contact number under the 'mobile' category. Anyone else experience this?
