I live in Germany, but I changed the user interface language to english. This setting does NOT change what TV Apps you get - I still get the TV Apps for Germany.
On my TV (LE40C652) I can select a different country in the Initial Setup Menu. I havent tried to change that, but maybe that setting defines what set of TV Apps you get.
My TV is a LE40C652, which seems to be available all over Europe. The corresponding US model is LN40C650 and uses a different firmware. I guess by changing the country setting, I might get other european Apps, but maybe still not US Apps.
And even if I could get Apps for another country, my IP address would still identify me as being in Germany, so foreign Apps might not work.
Check this site ( http://www.samsung.com/apps/ ) to find out what TV Apps you are missing. On this site ( http://www.samsung.com/us/samsungapps/ ) you find a link to a list of TV Apps ( http://www.samsung.com/us/samsungapps/Samsung_Apps.pdf ).
I compared those lists to the Apps available in Germany. The missing Apps are video streaming apps like NetFlix, Hulu, etc. They wouldnt work anyway, because their content providers have to check the receivers IP address to obey regional broadcast limitations.
Since you mentioned the FaceBook app - its available in Germany. I cant think of any reason, why it is not available in Italy.
I live in Italy and I can't use some interesting TV apps such as Facebook. I have a blu-ray player with 2010 Internet TV capabilities.
I have just read some interesting threads in this forum and my understaning that the TV apps developer sort of tag each app with the list of countries that the app is done for. Actually, I don't understand why this is done, is it simply a language issue?
Is there any way I can change settings so that I am seen as based in some other country? I have tried to change the language settings but this does not help Thanks for your support.
