I'm gonna buy the PSP GO tomorrow and I would like to be directed of referenced to a CLEAR guide on how to install CFW on my GO.

Basically, I have one small question. When I'm gonna buy my psp, I will probably update it to 6.35 and then install 6.35 PRO-B3. But before the installing part; must I install 6.35 PRO-A then install 6.35 PRO-B and update to PRO-B3 OR install PRO-B directly into 6.35 OFW and update it to 6.35 PRO-B3.
By the way, can we hack ALL psp go (6.35 & lower) or some have unhackable mobos?
Thank you!

Another off-topic question is : Can I use CWCheat with 6.35 PRO-B3 ? If yes then how?
