Unable to download apps in the android market?

This has happened to me before. If you can, you should wipe the whole phone and start fresh again. That should clear up problems it had before. I dont know what version your Android phone is running but if its in 2.3, resetting is in Settings, Privacy, Factory Data Reset. It may or may not work but its up to you if you want to reset it. After its done, ask your boyfriend to enter his gmail to sign in to download apps and see if it works. If not, then you need to update the phone if not, root the phone, install Clockworkmod recovery and install Cyanogenmod but thats if the phone really doesnt download apps.
