For download PSP stuff I recommend everyone to take a look at the PSP Wizard website, because it contains software downloads for your PSP firmware. For those who have bought your PSP for a long time, it is a pretty good chance that there is a latest firmware for you to download and keep your PSP up-to-date. The latest PSP firmware version is 3.52 and to update your PSP firmware simply enter and download your latest firmware for upgrade. By the way, the upgrade is free for everyone who owns a Sony PSP unit.
