I wanted to watch some of the Olympic coverage the BBC was offering. As most people know the Iplayer app is only available in the UK. This is a method to circumvent it. I have done this on my 51E6500 plasma, a 2012 model. This will only get you the necessary UK apps, you will still need a VPN service as the BBC does an IP check to see where you are coming from.
Go to the Smart Hub Screen
Place the cursor on the 'Samsung Apps' icon
A screen should pop up letting you change the region of the App store, choose the UK.
NOTE: The Apps you currently have that are not available in the UK will be deleted. They will come back when you switch back to the "US" App store however.
