i couldn't find the answer to this question while reading stickies. 'what's the real point of updating?' i'm running 3.2U and the usb loader and my friend said i should update to 4.2. i asked him 'why?' and he couldn't answer. i don't need the sd card loading feature. should i still update to 4.2? because even the new games seem to be working fine on my 3.2U and the usb loader.
