Question about Fairphone 2

You can also order the Fairphone 2 (without contract) directly from Fairphone. There you can choose all the back covers. It's no more expensive than at Digitec.

I can't say since when, but at Digitec you can now also buy the individual covers (in all colours that are offered).

At http://fairphone.faircustomer.ch/, the Fairphone is available in all colours: black, black-transparent, blue, blue-transparent and transparent.
