So from reading the stickies and looking around the net, I found out that only a PSP 2000 can have the custom firmware installed. I have a few questions regarding this. Is the PSP Slim and Lite a 2000 model? and also I saw Datel released a battery to mod the 3000, but someone mentioned the magic memory stick method not being up to date, so that the 3000 is STILL unable to install custom firware, is this true?
