well. it's very complicated process. you should open settings, go to applications and open applications management menu (it's the most complicated). then you should ask your friend to find cyclotron in huge list of installed application (alone you will spend about 10 hours, just ask friends to find it in about 1 hour), then click on it and find Uninstall button. It hides sometimes, just ask button to appear. remember - N9 is SMART phone, so it watching and listening you all the time. Good luck and be careful!
