A few weeks ago Justin Case released a root method for the previously unrootable Verizon Moto X. The method, "PwnMyMoto", uses three separate exploits to get the job done. T-mobile just released an update that fixes lots of the bugs in the Moto X camera and makes the camera usable. Picture quality is much improved with the new update. As expected at least one of the vulnerabilities used to root the Moto X has been patched. This has been verified by Justin Case. As a rule of thumb if you want root privileges on your device you should not accept ota updates.
