As iPlayer Radio is launched for iPhone, the BBC says it is also going to develop an app for Android, but that's it.
In a bid to revamp its online audio, the BBC has created a version of the popular iPlayer for its radio stations.
iPlayer Radio will see content taken out of the iPlayer and offered instead via a separate desktop and mobile service.
An iPhone app is will be available later today, with Android due to follow shortly.
However, the BBC says it has no plans to create apps for other platforms, including Windows Phone and BlackBerry. The iPad is missing too, but that won't be for long. In the meantime, the browser-based website has been built to work on any screen size.
The iPlayer Radio app will be restricted to UK use only at the moment, but the PC version will be available globally.
Commercially, given how small the BB and WinPho user bases are, it makes little sense for the Beeb to invest in platforms outside of iPhone and Android, but it's just another example of how far BlackBerry's star has fallen and how much ground Microsoft has to gain if it wants Windows Phone to be a true competitor.
