I recently read something about ED05 fixing "the missed call issue". Not infrequently my wife (also with a rooted Fascinate) and I will call each other, but the call never shows up on the other's phone...not even as a missed call. Is that what ED05 fixes? If so, exactly what do I have to do to acquire and install it? Right now our phones show Build number SCH-I500.ED01...is that what we're talking about?
