Instructions
Check a free proxy list to find a proxy that is based in the United Kingdom (see Resources). Ensure that the proxy has a good speed and connection time. Both of these values are given on the proxy list.
Navigate to "Settings" and then "Network Settings" from the PS3 main menu.
Choose "Internet Connection Settings" and then "Custom."
Choose a wired or wireless connection and then enter the authentication settings when prompted.
Choose "Automatic" or "Do not use" for all of the settings until prompted for "Proxy Server." Select "Use."
Enter the proxy address from Step 1 into the box. Finish the network connection settings. The iPlayer application will now recognize the PS3 as being within the UK.
