i got calls from a specific person about 50 times per day at any and all hours, i want to keep this number from even ringing my phone..... is there a way to block a number so it doesn't come through with the i850??? or a way to just have that particular number not ring at all? i know how to set it to a particular ringer type/tone but i don't want this caller to ever ring my phone again period, is there a way to do this??? thanks in advance kc
