Even set to english there are still some differences from the U.S. version. X and O button operates differently and the keyboard always defaults to Japanese. The keyboard can be in English if you use the select button. However I have read the tentative English manual of the FCC website and the U.S. version is called PSP 1001 instead of PSP 1000. Does anyone know if it is sent back to Sony can they reload it with the english software? Can it be downloaded from a website?
