You can't get out of sandbox in 4 days. It's just an illusion. If you are searching for inexpensive keywords, your site will definitely show up. for higher keywords, it won't it will be still in sandbox.
Where did you get those huge amounts of high PR links from? Any site would rank top with those kind of links.
4 Days? SEO doesn't happen overnight in my opinion. I'm with the "naysayers". It would be unlikely all those links were indexed so quickly.
