The BBC has offered official apps for Nokia's Symbian platform and an iOS-optimized website since 2008. Earlier this year, the BBC also introduced a BlackBerry shortcut app for its mobile website. The iPlayer website is also unofficially supported on Android 2.2 using Flash 10.1.
UK users can download BBC iPlayer for BlackBerry from the BlackBerry App World. The app is free and works on BlackBerry Storm 2, BlackBerry Bold 9700 and BlackBerry Torch 9800 smartphones.
The app will work over 3G, but for optimum experience you'll want to use Wi-Fi. We're not in the UK so we can't check to see if the app allows you to download programs for offline consumption -- as you can with the Symbian app -- but we're assuming this is a streaming-only application.
BBC journalists are currently striking over pension plan changes, so if you're looking for news content on your BlackBerry, you might be stuck in reruns for the next 48 hours.
