Hey so I just got my 2g ipod touch and I was wondering, if there is such thing as a silent mode (not a application)? Because when I bring it into class I dont want it to make a sound every time I get a email or something. Do I just put the volume to 0 or is there so way to turn off all the sounds instantly. OR when the ipod touch is in SLEEP mode then not sounds are created? Thanks PS-Dont want to create another thread, can you save your Email (USERNAME) with the Facebook application so you do not have to type it in everytime?
