Has anyone ever intentionally used the grip of death on the iPhone 4 in their favor? Let's say that an ex calls you, or simply someone you rather not talk to and need to end a call quickly, all you need to do is press that magic invisible G.O.D. button the left side of your phone *Locks on grip of death* "Hello? Are you there? I'm losing signal?!" haha Anybody care to share any stories?
