Canadian Nexus 4 users will likely get a notice on their devices stating the availability of the Android Jelly Bean 4.2.2 update. While it is a nice little update that brings some fixes it also annihilates the ability to enable 4G-LTE on certain carriers (like TELUS and Rogers in Canada, for example). Granted the 4G-LTE feature was a hack, and the Nexus 4 was never marketed as a 4G-LTE device, it is still capable of accessing those network speeds and has the required LTE hardware. So the 4.2.2 Jelly Bean update actually cripples this promising feature on the device. How will users who updated their Nexus 4's to the latest OS build feel knowing their device is capable of accessing faster speeds? Not too happy, I would guess.
