So I just got a PSP GO 6.60 and have been wanting to install CFW but I don't know if I can use the store or not after I hack. I've looked everywhere and could not find a good answer. So any help would be appreciated
No, same with online play, it all works, nothign extra. You are on the latest official firmware afterall, just modified. Again though, I have no clue if it can get you banned.
