It looks like the HTC Titan II isn't the only new smartphone that's going to be launched by AT&T on March 18. If BGR's reports (here and here) are correct, the second largest US mobile carrier will introduce other four handsets on that day - including the Nokia Lumia 900, which will join the Titan II in becoming one of AT&T's first Windows Phone LTE devices.
Unwired View, AT&T's Nokia Lumia 900, Samsung Galaxy Note and Rugby Smart priced. Should be out on March 18
