Access to Google's Glass headsets is still limited to a lucky few, but that's more than enough to include several curious coders. Some have had success identifying the hardware contained within, but others are focusing on the software. Cydia founder Jay Freeman posted the above image on Twitter this afternoon to show that he had gained root access on his unit, telling Forbes he relied upon a well-known Android 4.0.4 exploit to take control of its OS. The bad news? He hasn't been able to use it much yet, since the Explorer edition isn't quite ready for prescription glasses wearers. For now, the question of whether the same technique will work on eventual retail versions remains unanswered, as well as what it's actually going to be useful for. Steven Troughton-Smith suggests developers can use it to try out more complicated apps than Google currently allows, including always-on heads-up displays or camera apps. Overcoming any remote deactivation Google may try to enforce or loading your own unauthorized apps are also definite possibilities, though we're sure others will surface soon.
