Unless you have a personal political opinion about it. I personally support Iran, I support the Iranian government (as an existing middle eastern democracy), and I support the Iranian people. I am against oppressive theocracies, and I support Iranian citizens doing what is necessary to loosen or free themselves from the hold of how they express their faith being dictated from above.
In my opinion, any methods to help Iranian people to help them shake this control that aren't covert Western attacks on Iran or Islam are a good thing. Helping the protestors to communicate with each other is one of the most neutral, anodyne things you can do. For me, legitimate government is created through discussions, plans, and agreements among the governed. Any disruption of that is despotism. Maybe, one day, Iranians will be helping us protest.
