My iphone did not download anything?

When i'm going game center it says me that you did not use your id in itunes when i'm going to itunes it also did not showing anything.

Check your acount setting, or refresh your iphon if didn't work

In order to download free, or purchased: Apps, Games, and Media, you have to sign up, and Register, to use the iTunes Store, and provide Credit Card info.

And, you need to create your own Apple ID, as well.

The Error message tells me that you haven't done any of that, yet. Open the iTunes App, and click on the Store TAB, and then, choose "Sign In", and follow the prompts.

Later, you must Sync your iPhone to move your purchases on to your phone.
