Anyone else have this problem? It worked fine when I had the 3GS. I got the phone the day it came out and I'm pretty sure the internet worked last week in my office building. The internet works fine everywhere else. I can still make calls, receive and send texts, but safari won't load any webpages and apps that use the internet (Facebook) don't load. When I reset network connections it works for a couple seconds and then doesn't work again. Anyone know how I can fix this.
