Hardware modders have pried open Barnes and Nobles nook ebook reader, turning the device into an Android-based tablet PC complete with a free mobile connection.
Register: The multi-stage hack is documented on nookDevs. Part one involves a process called teardown, and this is followed by rooting. Obtaining root privileges gives users control of the device. The hack involves poking around in the insides of a nook with a screwdriver, as well as software modifications, and so is far trickier than unlocking an iPhone, for example. Users who follow the instructions will void their warranty, even if they are careful and competent enough to navigate the process without turning the ebook reader into something that can only be used as a bookend.
