BlackBerry Storm owners will now have the option to get the "mobile music discovery application" Shazam for their handset.

Shazam has been available via the BlackBerry App World since April but now offers full SurePress touchscreen support.

Not really grasping the concept of exchange rates, BlackBerry Storm smartphone in the UK will be charged a full $3 dollars more than US users ($4.99 compared to £5). iPhone version is free.

The full-featured version includes unlimited Tags, Tag charts, recommendations for similar tracks, biographies of artists, reviews of tagged music, discographies and the option to buy and share discovered music.

Shazam is currently offering a free, 7-day trial of the full-featured version, available for users in the US, UK and Canada.
