i was on facebook on my iphone and clicked the instructables icon in the apps section of the side bar and it went to safari and there it was, something i have been waiting for for ages (title ruind the suspence there)......THE INSTRUCTABLES MOBILE SITE!!!
then a popup popped up and it said add to homescreen or something like that because its a web app.
