How to use voice control on an iphone 4!

To the people that don't have the fancy 4s iPhone's with Siri (including me) did u know you can still do simple voice commands?

It can't set any reminders or can't answer any of your strange questions but it can: Play/Pause Music, Call, Dial, and FaceTime!

To do this, simply hold the home button down (located at the bottom of the iPhone) for a good 3-4 seconds till this blue screen pops up! Now just say your command!
