I just bought “PSP 1001K” version 1.05, please tell me I can update to version 3.11 form us.playstation.com, there is no harm to update U.S. 3.11 version?
if you got any game with it they come with updates. If you want to update just create a wirless network with your psp and pc and click network update. Dont turn your psp off when updating.
