My iPhone 4 is working perfectly in every way except one... In and around my apartment, I cannot access the internet. I can still receive phone calls and texts, but I can't get online at all. At first, I thought it was just a network issue related to AT&T, and didn't think much of it. But its been happening for about a week now. Last night, a couple of my friends came over, and they both also have iPhone 4's. Turns out they can fully access the internet at my house, with no problems. When I leave my house, no matter where else I am, once I get outside that 1/2 mile bubble, everything works perfectly. Wtf could that even be?
