I want to get a PSP and can't decide between GO or a fully hackable 2000. Also what's the biggest Memory stick you can have? Also is a modded PSP GO just on the cfw for 6.20 (forgot what it's called) just like a fully hackable 2000 on Prometheus 4 5.50 in terms of homebrew and iso compatibility and is a PSP Go just load games straight of the system or can you use the MSM and what's the biggest memory stick micro you can get? That's all. Sorry about bad grammar.
