BT has launched an app that will let its broadband customers access some two million hotspots throughout the UK on their iPad.

The app, which was previously available for iPhone and iPod touch owners, has been updated to include support for the iPad and is free to download.

Once you have downloaded the app, you will be able to get online at any of the country's estimated two million BT Openzone and BT FON Wi-Fi hotspots. No matter which BT Broadband deal you are on, Wi-Fi data is free and unlimited.

All you need to do is enter your BT Broadband username and password to start using the app.

John Petter, managing director, for BT Retail Consumer, said: "Millions of BT broadband customers already get free access to the UK's biggest wi-fi network. Our free app for the iPhone and Android devices has proved a huge hit with over 400,000 downloads to date, so launching an app for the iPad was naturally the next step.

"The app makes accessing wi-fi so simple you don't even have to think about it and represents real value to our customers at a time when more and more people are accessing the internet when they are on the move."
