Hey guys, want to seek some help from the members if somebody knew that before I will buy a PSP, I want to make sure that it can be customized. I found one store selling a mint green PSP with letter 'E' below the voltage on the bar code, after I check and found out that the firmware is ver. 4.01 which is pertains to unhackable (more or less), but most of the google searching that they are only emphasizing letter 'G' with 4.01 is unhackable, is there any one can help me to verify that the letter 'E' with 4.01 can be customized before I buy.... Thanks and appreciate your help in advance.
