Betting on Mozilla’s mobile operating system? There’s a good chance, then, that you’re kicking around a Geeksphone, one of the few devices known for running Firefox OS. Owners of the company’s Keon and Peak handsets can now manually upgrade their devices to Firefox 1.1, which — according to enthusiasts on the Geeksphone forums and Twitter — speeds up boot times, patches an assortment of bugs and tacks on minor navigational and display improvements. Naturally, users interested in trying the build will have to download and flash it themselves. Unsure how to proceed? Check out the Geeksphone forums link at the adjacent source link for tips.
