From PS3 Attitude: "UnoTelly’s UnoDNS product is a service that allows your PS3 to pretend to be in a different country to the one it is really in. Why would you want to do this?
Many PS3 users have more than one account set up on their PlayStation in order to access content in another region’s PS Store. For example, if you’re in the UK you may wish to download free content and demos from the US Store.
But if you try to use the US TV services, such as VUDU or Hulu while logged in to your US account, you’ll be faced with a message explaining that you’re not allowed to see that content. This is where UnoTelly comes into play. So, is it any good and how does it work? And what else do you need to consider?"
