For iPhone, go to the My Vodafone app's Wi-Fi Finder and click or tap 'Set up' - it'll guide you through the set-up process. For BlackBerry, click the Menu button and choose 'Setup'. Once it's all set up, the My Vodafone app will automatically connect you to any BT Openzone hotspot that's in range, as long as you have BT Openzone UK Wi-Fi access included in your pay monthly price plan. If it's not included in your plan, you'll have to pay BT Openzone each time you want to access their Wi-Fi hotspots.
