Have you been itching to become one of the first adopters of a Firefox OS smartphone? Then go grab your credit card, because the first Firefox OS smartphones go on sale today. Starting at $119 SIM-free, the Geeksphone duo are really aimed at Firefox OS developers who want to start building apps for the platform.

But you don’t have to be a developer to bag one, and Geeksphone is willing to ship all over the world.

Although Mozilla has stated that it won’t produce hardware for its upcoming Firefox OS, the company has teamed up with Spanish startup Geeksphone to offer a pair of developer devices. Called Keon and Peak, the devices are designed to provide developers with the opportunity to “tap the future of mobile” and get to grips with the platform that will soon be trying to steal marketshare from Android and iOS.
