Change is hard. Fortunately, sometimes you can make a change without giving up on the past completely -- and that's the case for the new Geeksphone Revolution, which lets you try out Firefox OS without burning your Android bridges.
The Revolution switches between Android, complete with Google Play access, and Mozilla's Firefox OS software, also known as Boot2Gecko. It's on sale on 20 February.
The 4.7-inch phone packs a dual-core Intel Atom 1.6GHz Z2560 microprocessor with 1GB of RAM. It boasts 4GB of storage with a MicroSD slot for extra memory, and an 8-megapixel camera with LED flash.
Available from geeksphone.com, the Revolution costs 239 Euros not counting VAT, although Geeksphone will knock off 20 euros if you get in quick.
Spanish company Geeksphone is the outfit behind the first Firefox phones, the Keon and Peak. The Geeksphone geeks don't have far to go to phone and tablet extravaganza Mobile World Congress, held in Barcelona in a couple of weeks, where the mobile industry gathers to shout the odds and show off their wares. We'll be there en masse to bring you the first news, videos and hands-on first impressions of Geeksphone's Revolution and the upcoming Blackphone, and the rest of the coolest kit you need to know about -- so keep it CNET.
