This is a tiny trivial thing but I'm up and running with a warranty replacement G4 and I have everything set up just the way it was except that the phone no longer makes that comforting little vibration when I hold the power button to turn it on. I don't know why that would be any different with a new/refurb phone than with the one I had. Does anyone know anything about that and whether it's configured somewhere? I've kind of gotten used to it over the past 11 1/2 months... Thanks!
