What is a TI OMAP 4428?


This tablet allegedly has a TI OMAP 4428. TI's site turns up references to a 4430 and other models, but no 4428. (Is it basically a 4430, or are the numbers as misleading as they are in PC land on Radeons?)
Its basically the same kind of device as the Kindle fire 1st gen, it has two bootloaders, I believe one is called uboot. Pc recognizes ti omap4430 when devices bootloader is screwy or wiped. More info on xda-developers
