Yes........However I suspect Wiki Leaks people to step up sooner rather than later and assist in communications..........they will bypass Irans control.
Wikileaks can't do anything for the Iranian people, they simply publish whatever hacked stuff they come across. Once Internet, TV and radio get shut down its game over for the protesters... UNLESS someone from the outside (like the US/CIA) decides to feed information into Iran via radio or other means. You can bet Russia is doing what they can in this area too in support of the regime.
