The ABC has had radio streaming in its iPhone app since it launched, but the option just got a lot more appealing with the addition of 19 more stations: 10 metropolitan ABC Radio stations and nine channels from Radio Australia.
Before you ask: I checked with the ABC, and while there are no immediate plans to add a similar streaming facility to the Android app, the broadcaster is keeping a close eye on Android uptake in Australia and there will be more Android apps in the future.
As ever, this is an option more sensible used with a Wi-Fi connection than over 3G. The ABC app is a free download for iPhone and iPad users.
