There's been a lot of speculation surrounding the possibility that AT&T's Atrix series will soon becoming a trilogy, with most of the chatter linked to a device codenamed "Dinara." However, some of this speculation could soon be converted to confirmation, as the Dinara, also known as the Atrix 3, has recently taken a stroll through the halls of the FCC under its surname MB886. Not much is revealed here, but this handset is definitely bound for AT&T's 4G LTE network. The documents also list support for HSPA+ / WCDMA 850 / 1900 and quad-band EDGE. Aside from a few more details concerning the phone's dimensions, rumors of the oh-so-popular dual-core Snapdragon S4 processor have also been floating around. Hopefully we won't have to wait too long to hear something from AT&T or Motorola Mobility.
