I think he's meaning setting it from loud ringer to silent mode, like if he had to last minute change it right before a movie started or something.. Rather than unlocking his phone, going to settings, then sounds, and volume or whatever.. I think he's looking for a shortcut to silence it in 1 or 2 clicks. I don't have my fascinate yet.. but if I figure it out I'll let you know. On my D1 I can hold the power button down and get a Silent Mode option. Does the Fascinate do anything like that?
