Hi! I am looking to buy a white PSP for my boyfriend for Christmas and have been reading through this forum for advice. I'm confused about this 1.5 v 2.0 issue and "homebrewing". One post on here was about someone having a 2.0 and wanting to get rid of it to get a 2.0 instead. Can anyone explain what this is all about please? Will affect the games that can be played? Thanks!
