One of the things I like a lot about with the iPhone is the prevalence of free, demo versions of apps you can try out before laying out your money for a program. For instance, Handmark division Astraware has just posted a Lite (free) version of its space-age racing game Phaze here at the iTunes App Store. The Lite version includes 1 race craft, 1 location and 2 difficulty levels. If you like the game, the full version ($4.99, available here) adds a Championship mode, a total of 4 difficulty levels, 15 more locations (with 64 tracks across all difficulties), and a total of 10 race craft (some are unlockable). Below is a video demonstrating the full version of the game. Phaze is available only for the iPhone and iPod touch, no other mobile platform.
