How to toggle/turn off 3g on iphone 5 with LTE?

I updated my software to iOS 6.1. Then I notice in the settings>general>cellular the toggle to turn off 3g was replaced by enable LTE. Our country offers free LTE up to April 2013. How will I turn it off (3g) if for example i would want to use wi-fi instead?

Mobile network that's how you do it
