Well I just received my apad i the mail, waiting for it to finish its second charge now (after completly draining the battery.)I plan to flash the RB 5.1 firmware to it, though I would like to backup the stock firmware that is on it now... or atleast find a copy of the stock firmware on the net before I go about flashing this custom firmware onto it.I trolled through a bunch of pages and a bunch of diffrent searches, I'm hoping someone can point me in the right direction.Also is there an app, or way that i can confirm what CPU is in my unit?Thank.
