A few weeks ago, I lent my iPhone 4 to a friend, and his little brother signed in to the phone with his Apple ID; problem is he doesn't remember his password or his e-mail password.
What can I do to remove his Apple ID?
iPhone 4, iOS 7.1.2
Hello evgen_,
Welcome to Apple Support Communities.
If I understand correctly, there's an issue signing out of an Apple ID on your iPhone 4. The article below provides a lot of great information about Apple IDs and it should help you resolve issue with your device.
If you're asked for the password to your previous Apple ID in iCloud - Apple Support
Learn more if you don't need to sign out of your previous Apple ID and instead need to sign out of someone else's Apple ID on your device.
Cheers.
