The hacks for the Barnes and Noble Nook Color keep on piling on, first we could root the device to get Android on and then install applications such as Angry Birds. Now we have a way to make the processor run faster from the default 800 MHZ to 950 MHZ without increasing the voltage.
The new hack even though it overclocks the Nook Colors built in processor, actually lowers the voltage of the device, making it so you have LONGER battery life, which might be appealing to allot of people. Also the hack also fixes the screen flickering bug which a fair number of users have reported.
Some fixes by the same author that are on the horizon is bringing it up to 1 GHZ of processing speed and eliminating the 2 point touch limitation.
If you are feeling frisky and want to update your Nook Color using this new method, all of the instructions are found on XDA Developers.
