With the launch of the Lumia 710 for T-Mobile, Nokia is attempting to do something pretty ambitious: make Windows Phone the smartphone of choice for the masses. And the company has put together a pretty compelling package for $49. Wrapped inside a solid design is a fast 1.4-GHz Qualcomm processor running Microsoft's inviting and user-friendly OS. Nokia is sweetening the deal by adding some unique goodies, such as Nokia Drive for free turn-by-turn navigation and an ESPN app with exclusive content. Does the Lumia 710 have what it takes to woo first-time smartphone shoppers?
