Mail, messages, AppStore and safari not working on iPhone 4 (iOS 7)?

I go to open mail and it won't update, the AppStore has the categories at the bottom, but it stays blank and doesn't load. And Safari says "Safari could not open the page because the server stopped responding. I'm connected to good Wi-Fi and it's working because my other devices are working on the internet.
My date and time is on set automatically. And I'm on ios7.

You could back up your phone to a computer then reset everything and put the data back on. I had this problem but it was my Wi-Fi antenna inside my phone that was broken. So if thats the case then either do a self repair by looking up online how to replace the Wi-Fi antenna. Or go to a shop and ask them to see if they can find out what's wrong with it. Hope i helped

Settings - General, scroll down to the bottom. Tap reset and then reset network settings. Note this will knock you off of Wi-Fi so you will have to rejoin it manually.

  • Safari not working on iphone 4? I used cydia to jailbreak my iphone 4 and after that safari would just open for a second and then go back to the home screen. I used ifunbox to delete cydia from my iphone and it's not there anymore, but safari is still not working on my phone. Is there anything i can do? I have already rebooted my phone numerous times and this hasn't done anything.
  • On my iPhone, my mail, calendar, safari, and maps won't open Hey… So I tried jailbreaking my phone and it didn't work. Anyways, after I stoped trying to jailbreak it, I realized that some of the apps that you can't delete (Mail, Calendar, Safari, and Maps) won't open! They just keep crashing! I really would like these apps to work again so I can use them while I'm on the go. I already tired the dumb little things like turning my phone off and then back on… But it doesn't seem to work!
