Yeah prior to iOS 5 our phones where setup on the same ITunes and it would see both of our phones as 2 separate units, the apple Id was always on the right phone, and the MY Computer would always show the correct iPhone name. Now however, it shows her iPhone name in my computer regardless which one of ours is plugged in but ITunes does show the correct phone at all times, so that's good. My phone shows my correct apple id and uses mine when I open iTunes or the app store on my phone. Her phone in the settings will show her apple id as the one shes logged into, but in iTunes and the app store it will use my apple id. Her phone has never been logged into my apple id before this, so I have no idea what is causing this.
