Nokia Lumia 900 is a great new Windows Phone, now just exclusively available on AT&T for only 45 days. According with WMPower User, T-Mobile will get the new Nokia Lumia 900 this summer. Not happy with the Lumia 700, the magenta carrier will ad another 4G Windows Phone. We assume this will run under 42 Mbps HSPA+ network.
Stay tuned for more information.
