I really need to do a variety of things on this site, but I haven't had the time. The podcast, and putting the podcast on iTunes, will likely have to wait till a few days from now. Same for updating my sale page (the ESN minutes are gone, but I think I could get some 60-minute cards for $12.50).
But to help some people out, the LG 3280 has a vibrate mode. Just press and hold * and voila, Manner Mode. :) Do it again to switch back to normal mode.
