I updated my Iphone last night to the 2.2.1. it was working fine until today. I could not get Safari to connect to any websites. It kept telling me that Safari cannot cannot open the page because it is not connected to the internet. When I connect to my Wifi at home, safari works. But I'm at work and there is no wifi. I tried all the restarting/rebooting, Airplane mode, resetting. Any advice or Tips?
