My sister received a hand-me-down iPhone. When she tries to update her apps, it still asks for the password for the previous owners iTunes account. How can I change it so it asks for her iTunes account?
Sorry, but that can't be done. If the apps were purchased by the previous owner, then THEY are the rightful owner of the apps, and their ID is the only one that can update the apps. You can either get their password or repurchase the apps on the correct ID.
