It was out for mobile phones for last...err... Year or even two... also there is undersea wersion called Deep... Also, both games are made by Fish laps...
I had Galaxy On Fire for my rusty K818c, it was the best mobile game I had and I loved it - until my analogue stick broke and I can't play it anymore. Fish Labs makes awesome mobile games.
I'm not going to buy an iPhone for this, although it'd be an awesome portable substitute for Freelancer.
