Hey. My brother and I are about to buy a couple PSPs mainly for the ad-hoc multiplayer gaming(especially the GTA games). But before we invest a couple hundred bucks, we had a few questions that maybe you guys could help us with: 1. Can you play ad-hoc multiplayer on 2 custom firmware PSPs? 2. Is it possible to tell what firmware is on a new PSP before you buy it? 3. Basically any PSP 1000 - 3000 is atleast semi-hackable and capable of temporary CFW as long as the firmware is below 6.37 right? 4. Would you guys recommend we buy used fully-hackable PSP 1000/2000s over new PSP 3000s? With the 3000s don't you have to reinstall the firmware everytime you power it on(does that get annoying)? 5. Is there any place you can buy new 1000/2000 models online? Thanks for any help! P.S. I searched for about an hour trying to find the answers on the 'temp but couldn't find much.
