Maybe an iPhone case developed to magnify the vibration sensation? That would be useful to the use of the phone in general, not just to wake up. Actually, it would be useful for me - and I am not deaf. I keep my phone on vibrate all the time and when on the streets I can only feel the vibration about 20% of the times someone calls me. And I usually i HEAR the vibration, not actually feel it. Becoming a hardware company is a little to far from you? :)
