Instructions
Go to the site in Resources and scroll down to the black "Download Now" button. Click the button and download the file to your desktop.
Connect your PSP to your computer using the system's USB cable. Turn on the PSP and navigate to the "System" tab of the menu, then choose "USB Connect."
Navigate to the root directory of your PSP. This will show up in "Finder" or "My Computer" as "PSP," "Removable Disc" or "MemoryStick."
Open the "PSP" folder, and within this, the "Games" folder. Right-click within the "Game" folder and choose "New Folder." Call this folder "Update."
Place the downloaded PSP update file in the "Update" folder, then eject and remove your PSP.
Connect your PSP to a power outlet and navigate to the "Games" menu. Choose "MemoryStick" and select "PSP Update." Wait for the update to launch, then press "X" to confirm the update. Don't turn off your PSP or disconnect from the power source while the update is installing. In about two minutes, the PSP will display a message that your update is successful. You can now access the Internet through the "Internet Browser" section of the menu's "Network" tab.
