I got a psp slim star wars edition over the holidays and was getting out of the car and busted the screen. I no longer have the reciept from the store. The psp has custom firmware on it. Any suggestions on getting it fixed or replaced? I can't see the screen to replace the firmware. Will sony repair it with the custom firmware? How hard is it to replace myself? I found some sites selling replacements, but none that specified the slim model. Are the screens the same? Thanks.
