Mute/vibrate switch included in replacement cable?

Hi,

I want to replace my iphone4 CDMA mute/vibrate switch but am not sure if your headphone jack cable has it included. I will alert you to the source of my confusion so you may correct it or clarify it to me.

The parts page for the iphone 4 (CDMA) says that the headphone jack and volume control cable includes the vibrate/mute switch. However, following the link for that item, the product overview for "iPhone 4 Headphone Jack & Volume Control Cable (CDMA/Verizon)" says "No volume button or mute switch is included. This is only the cable that connects the buttons to the logic board."

Please clarify.
