Someone pointed out to me the unlocked Blackberry 7105t for use on cingular's network. If anyone has one of these, maybe you can answer this question. If a call is coming through and it's set to either ring or vibrate, are you able to silence the incoming ring/vibrate WITHOUT taking it out of it's case/holster? When I'm in meetings I don't like taking my phone out and pushing end, I just want a button or something on the side of the phone that will silence the ringer but not immediately cancel the incoming call.
