I bought a lumia 710 a month ago and am now sold on windows phones. Now I want to get one for my wife. I have 2 options with t-mobile. Radar and lumia. From what I cab see the lumia has a better processor while the radar a front facing camera and a slightly larger screen. Anyone have experience with both of these phones and could tell me if one is better than the other. I'm month to month and the radar is slightly more on eBay.
