So I downloaded ios 7 on my 64g iphone 5 today. Me and my wife share a iTunes account. She has a 16g iphone 4. Hers is not yet updated. Well in settings under message tab it has both of our phone numbers and both emails. I can un-select her number and email and it's fine but when she un-selects my number and exits, it auto selects it soon as you go back into it. This is making it so she is getting all the messages I send and recieve to other phones. This needs to change ASAP. How can I disable her phone and email permentaly from my phone and permentaly from hers also?? Driving me crazy.
