Though Google Glass runs Android, it's not exactly as wide open as your typical Android phone. And given its spot as the most futuristic tech available right now, you know hackers want to tinker with Google's specs. Legendary hacker Jay Freeman, famously known as Saurik who created the Cydia app store for iOS jailbreak phones, did just that. He's already gained root access to Google Glass.
How did he do it? Freeman discovered that Glass ran Android 4.0.4 so he modified an exploit from another hacker named B1nary that allowed for root access on Android 4.0.4 phones. He told Forbes:
"It took me two hours while I was having dinner with friends at the time. The implementation from B1nary is for normal Android tablets and phones, I learned how it worked and then did the same thing on Glass…which was quite simple." More here.
