It appears I just received an update to S3 and now when I go into settings, I can not change sound to vibrate as I could before. Things all over have changed. I am tired of the S3. I was apprehesive about going to a smart phone because of potential increase in cost and was told no it won't with the unlimited plan. I am so ready to tell verizon to take a long walk off a short pier and go back to ATT.
