on my internet at home (at&t yahoo) my safari on my iphone works perfectly. but at my apartment (I believe it's cable, not sure), safari hangs on certain websites. it loads google fast. yahoo loads slower than usual. and on a lot of websites like hackint0sh, macrumors, televisionwithoutpity, it never fully loads (aka hangs). and youtube takes FOREVER to load a full clip. can someone please tell me why??!! is it due to the router? ports? I even tried opendns on my iphone as well. please help!
