The first LED of the three to the left of the i/o button (the one with a little phone icon painted under it) flashes green constantly, about once every two seconds. According to the very end of the pdf manual, this indicates the phone has reception. It kind of reminds me of Homer's "everything's OK" alarm.
Any idea on how to disable this "feature" other than a piece of electrical tape?
Apologies if this has been addressed before; I did a forum search but probably not as exhaustive as possible.
