No, check the market for VooDoo Root Keeper, since you have root, save it with that app. Once saved click "Temp. unroot" and you won't be rooted anymore. Once you're on ICS open the app back up and click "root" and will restore root with no problems. PLEASE make sure you uninstall safestrap or bootstrap if you currently have it, and i don't mean just uninstall the app, go into the app and uninstall Boot/Safestrap, THEN uninstall the app.
