Okay, we all know Rule #34. Unless you don't, in which case you're probably better off not knowing.
But I'm just wondering what the Rule # is for "There's bound to be an iPhone/Android app for that..."? If there isn't one, we ought to assign one. Is Rule #42 free?
Also, the Rule # for "yes there is, but it's not compatible with the iOS (or indeed iPhone) I've got?"
