For everything a phone could possibly be...
and some. I use mobile banking, UPS tracking, MacRumors (of course), UrbankickOakland.com (workout schedule), berkeley.edu (alma mater and CalMail website), Calbears.com (Cal's official athletic website), maps (everyday that I'm on the road), weather (everyday), youTube (almost everyday), IMDb for movie picks, Netflix, AppleInsider, FoodNetwork, BART (Bay Area Rapid Transit Train), ESPN, Kiowa Casino, SFSU.edu (other school and email website), Gmail, KRON4, KTVU and Powwows.com, and a bunch more. 😛😎
