App Store is the wrong language I changed my iTunes account location to German (with an Austrian credit card) in order to download a certain app that wasn't available in Danish (my primary language). I was now able to get the app from the German App Store. Afterward, I set the location back to Denmark and entered the Danish credit card that I was using before. 

Problem:
When I now visit the App Store (on my iPhone), it is still in German. How do I switch the iPhone App Store back to the language that is set in iTunes? iTunes has got it right, but why doesn't my iPhone see the same status?

I expected that it would be enough to just plug it into the PC and let it sync itself, but that wasn't the case. I've just synced the phone with the PC and that went without problems, but the iPhone App Store is still in German while the PC iTunes has the Danish account ("Country/Region: DNK").
Open Settings and go to Store. From there, choose Sign Out if you're already signed in and then sign back in again. If you were not signed in, sign in now. Now check the App Store. If necessary, restart the device.
