To use text messaging and navigation on Google Glass, users currently have to pair it with an Android phone and install the Glass companion app on their phones. This will change very soon, however, one of the Google representatives in its New York office told me when I picked up my own unit yesterday afternoon. Glass, the Google employee told me, will soon be able to handle these features independent of the device the user has paired it to (and maybe even independent of the Glass companion app). While Glass will happily work with any iPhone over Bluetooth or use any Wi-Fi connection to get online, iPhone users are currently unable to get turn-by-turn directions through Glass – one of its killer features. Those direction are pretty useful while you are navigating a new city and they do show off the power of location-based apps on Glass.
