i can understand your frustration as with regards to bb I have been told mine does not exist. I also want to believe it does not exist however i live my life like it does. The only thing you can do is actually live your life like nothing is wrong and cross your fingers. Wait for some one to actually comment with regards to your precieved problem or ask a trusted person to comment.
