cannot deactivate mobile theme

Hi guys. Having a problem with switching a mobile theme off in WPress 3.5. I updated jet pack and Activated one of its options: Mobile Theme. I am still building my website but am stuck with mobile version. After the look of a mobile site did not work well I deactivated the theme and then removed it. For some reason it’s still there and there is no option to activate/deactivate it. I just can’t figure it out.
Thanks for any tips.
