[ah heh-heh-heh HEY!!]

is there some way that you can change what your firmware shows in system info?

[zackfair_13]

as of now i think you cant. and i guess you never can

You could modify the CFW...... Its possible but you need a brain.

I heard once that you can with a HEX Editor.
You download the Custom Firmware and press

CTRL + F

then search for m33. Then Replace m33 with whatever you want.
But i havent tried it. If you decide to try it im not responsible for any damage.
