How to delete someone else's iTunes ID from an iPad?
Long story short, my son stayed at his aunty's place and she signed into iTunes via his iPad in order to download Garage Band for him. Whilst I have returned the user account to the previous one (i.e.: mine) and it shows up in Settings, for some reason when I now try to update apps etc I am prompted for the other (i.e.: my son's aunty's) account. How do I resolve this issue? Thanks!
