Gaming How to tell firmware from box

[SFenton]

Hey,
I want to buy my brother a PSP. They only have 3000s over here though.

Does anyone know/remember their serial number or one that would "reveal" the firmware?
I only have two options:
1) Basic bundle
2) RB:U bundle.

Thanks!

3000 can only temporary been flashed.

buy an used with datecode below 8c

And only on 5.03 official firmware. RB:U stands for?

I can't buy used, I'm in japan and there are no gamestops, just an Exchange.

Buy off Amazon; just make sure to check the ratings so you know if they deliver as stated.
