Hey modders I need your help.  I'm looking to get a psp-3000. However If I buy one new from the store, I will not be able to install custom firmware on it so I can run my backup isos of monster hunter. I need a psp 3000 on 5.03 firmware or lower, so I can install custom firmare on it. If anyone can please let me know where I can get one with this firmware, or already custom firmware enabled let me know! Also if anyone wants to make a trade. I'm looking to sell or trade my iphone, its a silver 2g, with a custom chrome red logo. It also is unlocked and jailbroken on 3.1.3. Again, Please Help!
