I tried. I held in the Home button, and after the tone, I said "call Rhonda (wife). It said back to me, 'Call Rhonda'. Then it called her. No voice training. I said, 'call Kevin'. It says, 'Call Kevin home or mobile?' I say mobile. It says, 'calling Kevin mobile'. Fuggin awesome. Then I have to mow the damned grass. So I slip the 3GS into my Belkin sport armband, pop in my (non-Apple) earphones. I thought, lemme try something. I click and hold on the little clicker until I hear the tone, then I say 'load playlist Favorites.' It says, 'loading playlist Favorites.' Sweet. Then I hold in the clicker again and say, 'shuffle'. It says shuffle, and away we go! Ain't technology grand? I love this thing!
