I found my newer model of PSP easy to hack and I wanted to help a friend who has the older Model. It's a PSP1002 with system software 3.8. Can it be soft modded? I did read the hacking/modding FAQ but I just want to be sure. And, do I need to upgrade the software to 6,20 using the link provided in the tutorial? If I can upgrade to 6.20, do I just have to then download 6.20 pro and follow the installation steps? Is there a chance of bricking it? This model came with a 32 mb memory card. Can I use a 4g memory card?
