Anytime I try to update my apps and click update all my sisters email comes up and not my email. It wants me to sign into her iphone account, when really I need to sign into mine. I have no idea why her email pops up but not mine. Also anytime I plug my iphone into the computer I get my sisters apps on her phone and anytime she plugs in her phone to the computer she gets my apps on her phone. Anytime I login to itunes I sign into my own account, as does she. I just have 34 apps that need to be updated and cannot use any of them because my email wont show up, but hers will. And she does not want me signing into her account on my phone, which I totally understand, which could make matters worse. Please helpp! This has been going on for over 4 months!
