Perhaps we shouldn’t think that the mysterious “X” phone by Motorola we’ve been hearing more and more about lately is just limited to one model after all. If you recall, we casually mentioned the possibility of Google introducing the “X” phone as potentially a new line of smartphones– not just one smartphone. Well, it appears that particular rumor may hold up more weight than we thought before. According to an anonymous tipster, at least two versions of the Motorola X are being developed behind closed doors: a main “X” phone and an “M” model— similar to the DROID RAZR M variant from the DROID RAZR line of smartphones. Specs-wise, the main phone will feature a 4.8-inch HD display, 2 GB of RAM and feature Android 4.2.2 (as of now).
