Google has announced the availability of Google Maps for mobile version 2.2. The software, a version of which runs on the iPhone and iPod Touch, includes integration with public transportation systems for retrieving directions using public transit. A video demonstration is available:
Version 2.2 is available for BlackBerry and other Java-enabled phones, however Google says they're "working to bring public transit directions to Google Maps on other devices, so stay tuned!" Giving the timing, it seems to be a reasonable possibility that such capability could be included with iPhone/iPod Touch software 2.0, expected on Monday.
