hi guys, new use here. just got my psp and have been reading many post and forums on how to downgrade/upgrade to get the best out of my psp, i must say that by now i am confused, some sites tell you one thing while others tell you something else. I currently have a 2.60 and have not done anything to it.. my main goal is to just play isos on my psp, can you please tell me what i need to do? i have read i have to upgrade first and then downgrade and i am cofuesd. i have read the psp sticky and still not certain about what to do, i apologize if this has been asked before, i have a ic1003 , version 2.60, thank you..
