I have dropped my i-phone.  It is working perfectly despite the fact that the glass is completely fragmented.  I neeed my phone; it is my comfort blanket and I can't imagine driving without it.  Not that I use it when I drive (obviously), but because I know that if there is a problem it is there for me to use.  My next course of action is a visit to the Apple Store, where my phone will be taken away (arrgghhh!) for repair.  Tough!  The sad twist is that Son's phone is insured for just this type of problem, and mine is not!
