iPhone users rejoice! Google Glass will soon add more support for iPhones, allowing the iOS-powered smartphone to be paired with Glass in more ways. The important support coming to Glass will allow the headset to access your iPhone's text messages and navigation, two useful features of Glass.
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, but the software will currently balk if you ask it to give you directions while it's connected to an iPhone.
Current Glass compatibility with iPhone is rather limited; Glass can pair up with an iPhone through Bluetooth for data tethering, but that's about it. Bringing support for text messages and navigation is a huge boost and will open up the potential Glass market when they launch sometime next year.
