Rumors about a purported Amazon “Kindle phone” are heating up, this time with the Wall Street Journal now reporting the device is in fact a reality and could launch as early as this year. According to their inside sources, the device will feature a display between 4 and 5 inches (but that’s pretty much a no brainer), and is currently in its testing phase with mass production scheduled for late 2012 or early 2013. Really, it’s no longer a question of “if” for an Amazon-phone, only “when.”
