So just following a youtube video I installed something called pro-b on my PSP 1001 with firmware 6.20. Should I upgrade to 6.60, does that actually make anything on the psp better/less buddy? I'm really new and alot of the info on the sticky doesnt seem to load properly (pictures and what not). Is there a list of dos and donts for this, like can I connect to wifi, is there anything to avoid doing, stuff like that.
