iOS: There's no shortage of GPS apps for the iPhone, but most come with hefty price tags attached. Telstra's Whereis app is an unusual exception: it offers turn-by-turn directions for Australians, and it's completely free.
The app appears to include most of the standard features you'd expect in an app: the ability to choose driving or walking, exclude toll roads, and quuck search for points of interest. Its runs on iPhone 3GS and 4 models, iPad and iPod Touch (though the latter would need a Wi-Fi hotspot connection to be of any practical use). Telstra customers who use it won't have data for maps counted against their usage allowance. If you've taken it for a spin, tell us where you landed up in the comments.
