iPhone isn't the only mobile device on the market with a growing game library. Taito seems to agree, refusing to leave Blackberry users in the dark for new gaming content. The classic game dev has revealed two of its prized licenses -- Space Invaders and Bust-a-Move -- are now available for the working man/woman's mobile device. Each title is available for $4.99 and features two control schemes: Touch screen control and using the device's keys. So, the next time you spot a frustrated business person in public eyeballing a Blackberry, just assume they're trying to beat a high score and not doing real work.
