German online retailer Cyberport is selling unlocked Lumia 710 Windows Phones for €169.90. There is a bit of a catch, for the €169.90 price you are purchasing either a black/magenta or black/cyan Lumia 710. If you want the all black Lumia 710 you do have to pay €179.90.
The Lumia 710 is the mid-brother between the Lumia 610 and Lumia 800 Windows Phones. It packs a 5MP Autofocus camera with HD video, 1.4 GHz processor, 8 GB internal memory, and an amazing 3.7″ 800 x 480 pixel touchscreen with ClearBlack technology.
