I can confirm it is not working for the Dutch iTunes Store on my iPhone 4. I think whammink is using a non-Dutch ID and is logging into a non-Dutch store, UK or US maybe? Even if iOS is set to English, the iTunes store of the Netherlands store is in Dutch language and the App is clearly in English in his screenshot.
I can confirm that. Also in Italy is working only if I log in with my UK itunes ID. If I use the Italian one the option is simply not there.
I suspect that this is the case for all European Countries but UK....
