Hello! My old Apple ID account has been deleted and signed out of my iPhone (in iCloud and iTunes/app settings). New account has been logged in. Yet when I try to update/download apps from App Store app, my phone still asks for the password to the old account that doesn't exist anymore! I put in my old password and of course it doesn't work. What can I do? I also have a factory unlock on my phone, completed in the uk. Thank you!
