The much hyped music streaming service Spotify has extended its mobile reach significantly today with the release of an app for phones powered by the Nokia-led Symbian operating system. This follows earlier clients for both iPhone and Android and means that the service will now be accessible on millions more handsets from Nokia, obviously, along with Sony Ericsson and Samsung which also support the platform. Unfortunately, for once users in the U.S. will have to wait longer as Spotify has delayed the launch of it's service there until the new year. Phones powered by Symbian far outstrip the iPhone and Android (for now) in Europe where Spotify is currently available. Today's release should see the company strike further carrier deals or at least extend their current offering with mobile network 3, leading to more 'back door' or 'feels like free' premium subscriptions.
