I've been getting nuisance call and found this site. I downloaded the app and then the silent tone with the intention of allying this silent tone to the nuisance numbers. After downloading it from this site, my vibrate function comes on with this silent tone too and all other tones. I deleted this silent tone from iTunes and synched my phone again and the silent tone has now disappreared from my tones section on my iPhone - however - no matter which tone I apply to the ring noise now, I constantly get the vibrate coming on, no matter which settings I use to turn it off as well. my phone was fine before downloading this silent tone from this site. Can you give me any advice please. Thanks.
