Бесконечное кольцо загрузки iTunes и App store

I have translated your problem to English.

Endless iTunes and App Store loading ring

When I try to download an application, it tells me "Apple Media Services terms and conditions have changed". I click "OK" and it goes to some page where at first there is a ring with the text "loading" and after a few seconds it just goes to a screen with a loading ring and it does not load. It just spins in a loop and that's it. It's the same story with iTunes: I try to download an application but then it just knocks me into the same loading ring

Check your network connection and try again.
