The offer is without the memory stick. You have to make that yourself but you can do that with a PC and cardreader (use the PSP as a cardreader
) only. That means, you don't need a modded PSP to create the special memorystick. It is said that memorysticks below 64Mb and of 4Gb and higher can't be used because of the internal structure.
You can also buy a pack with a memorystick included, but it's a 4Gb so unusable for Pandora:

If your brother has a Slim, I highly recommend this one:

Google for "pandora easy installer" or "umps" for easy installers.
Really? I was going to buy a pandora's battery and 8gb, magic stick memory card for a psp fat that I was going to get a for my birthday.
