Iranian citizens use of electronics as a political tool

It seems the outside world can only understand what is happening during the aftermath of the Iranian presidential election through electronic devices. As seen in the tweets of thousands of people protesting Mahmoud Ahmadinejad reelection and through the gory iconic photographs and videos on mobile devices of Neda's death, the new symbol of rebellion in Iran. The photograph along this article is of a protester taking a picture of herself on a cell phone camera to arrange a protest. The article is interesting, but the photo speaks louder to me in understanding the transmission of communication in this muted country.
Here's the link to the BBC article entitled Arrests in new Iranian protests.
