iSynth is a new and FREE iPhone app that brings Microsoft's amazing Photosynth technology to your iPhone or iPod Touch.
"iSynth brings much of the functionality of the original Photosynth to the iPhone, and for the most part it works well. In fact, the touch-screen interface makes the experience even more intuitive than the original."
