I'm having some confusion regarding voice control vs Siri. I just upgraded from an iPhone 4 to a 5s. I'm used to being able to access voice control on my 4 via my car speakerphone for dialing numbers, and occasionally by just pressing and holding the home button. Now that action brings up Siri, which I can still use to dial numbers. Of course I realize that Siri can do much more. What I'm wondering is if Siri completely replaces the old voice control, or is it still possible to bypass Siri and use the old voice control? Does the 5s have both voice control and Siri, or just Siri?
