My wife and i both have iphones. Even if i "sign out" under the store tab and she signs in she still sees my apps and vice versa. This is SO annoying!
Also how do you tell iTunes that the app order on my iphone is the way i want it to be!!!! Stop changing my iphone apps when i sync with itunes. WHen you select sync apps it should sync the apps the way they are on the iphone NOT the way they are on itunes.
When you open iTunes on your computer, you will see everything in iTunes, doesn't matter who downloaded/added it.
Ideally, you both have your own computer logins with your own iTunes library and all other data (contacts, calendars, files, documents, etc.)
Then you only see your stuff and she only sees hers.
If you still want to use the same computer login, plug in your iPhone, open iTunes and set it up as you want and your wife does the same. Add/remove whatever you want.
They are different devices and iTunes will treat them as different devices.
But everything in iTunes will still be seen by both of you.
I have a similar issue. My apps are showing up as an optional download on my wife's phone hers are not showing up on mine. Maybe because she doesnt have any new apps that I don't already have I will have to double check that. It's also odd when I go to update the five apps it asks her to enter apple password but it has my apple ID. I checked the settings on the phone and it shows that she is logged in under her account so why is she being offered my apps? Does it have something to do with home sharing? By the way we both have different apple accounts and use different computers.
