For those who have etisalat as a service provider, i have found a program that allows you to bypass all blocked sites. It works great, actually sends ur requests to different servers accross the world instead of sending it to the server here. All you have to do when you install it is select the mode that reads invisible. And that autmaticlally hides ur ip from etisalat.
You can download the program from this site:
