I have motorola v3i cellPhone it's possible when i closed flap and listen music?

Answer 1

If you are using iTunes, there should be no problem. It will continue playing even as you close the flap. In fact the side buttons adjust themselves to become volume control keys.
Not sure if this works with the built in moto media player. Stick to iTunes if you have it. It is a much better interface

Answer 2

yes u can. when ur music's playing, minimize the application (i think by pressing the middle button with the lines as symbol).
