One of my friends got the new iPhone 4s as a gift from her boyfriend, but a week after getting the phone, they had an argument and broke up. Her exboyfriend is now saying he wants the phone back because he paid for it and bought it outright from Apple under his name. We live in Melbourne Australia so I'm not quite sure of the laws. Who is right legally? Is my friend able to keep the phone if it was given as a gift?
