So, today I just noticed that you can double click the Home button when the Iphone is asleep (Is that what it is called when it is still on but the screen is not) and the music controls will come up without having to unlock the Iphone. so this may be old news but didn't see a post for it so I thought it could be handy to know. Oh and my double tap of the home button is not set to show ipod controls but the favorites list.
