Someone posted question about why their iphone couldn't access app store. In this "help guide" (http://support.apple.com/kb/ts1368) it focuses ONLY on Wifi and router, then says: " see troubleshooting Wi-Fi network" Really? what about the problem on iphone? Please help. I have the same problem. Wifi works, I can go on internet, do all the stuff I normally do, but neither the app store works or YouTube app. All the settings are OK, it just stop being able to connect to the app store. I have the latest OS on the phone. I updated it through iTunes, but still cannot access App store. Can anyone help, without focusng on the router that works just fine with 3 other iphones in the houss?
