I've got my account suspended twice. What error do you get when you try to sign on. The only real thing to do is call Sony (didn't work for me I was told to call the Eu Sony and didn't want to make long distance call) I think I got suspended for gamesharing. The first ban of mine was only for 2 days but the next was for 10 so I'd just wait it out, it's not terribly long.
