But what our source has circled for us on a leaked internal memo detailing the update, is more interesting. Apparently there is a Kernel exploit that was allowing hackers and modders to unlock the bootloader on the three devices. It appears that this is something that we told you about back in April, and considering Motorola's feelings about unlocked bootloaders, it is no surprise that the wholly owned Google subsidiary is closing it down. We're just surprised that it took so long.
