Question: how could i see the filtered sites .i'm in Iran THX I use adsl ISP? 

Answer: Connect through a proxy server. Search for public proxy server. Setup youre browser so that it uses the proxy to connect to the web sites. Tha main ideea is that you use the proxy as an intermadiary between you and the site so youre ISP sees a request to the proxy server, not to the site you want to access. You should try different servers because some are really, and I mean really slow :)
