Hi, I gave my iPhone 4S to my girlfriend when I got my 5S. When I backed up her phone to my computer and did a clean install, I restored it from her backup. Her apple id is listed under "iCloud" and "iTunes & App Store" in the control panel, but when we go to update the apps in the app store, it still asks for my apple id password. What did I do wrong and how do I change it? Thanks!
