I tried clicking on those links from my iPhone it says these apps are not available in the UAE app store I must change to the US app store
When I hit change, the app store opens with a blank white page.
If I click on change store on the top right, nothing happens, if I click again, it says cannot connect to iTunes store although I am connected to WiFi and have a data plan on my phone
I even tried using my VPN on the iPhone with no luck
Finally it worked thanks to the hint that the iPhone warrior gave me
I did this: 1) Opened AppStore, went to Featured (bottom left), then scroll down and choose your Apple ID: firstname.lastname@example.org , 2) then choose View Apple ID, and then change country/region and payment info. After that I signed out of App Store (do number (1) again but choose Sign out), signed in again and tried to download one free app and I was told 'u may do so only in NZ App Store, you'll be switched now to it' and surprise, surprise I finally was. I did ithis on my iPhone so don't know if it works differently on iTunes. Hope it will help someone. I was confused when realised it didn't work (before I signed out and signed in again)
