Persian folks (Iranians are not Arab as I'm sure you must know) are plenty tech-savvy and apparently lots of images and first-hand accounts are leaking illegally via Twitter, YouTube, e-mail, Skype, etc. I guess we can't get imagery like that from North Korea because cell phones are banned and even if they weren't banned, folks there can't afford a bowl of rice, let alone scrounge for a black-market Blackberry or iPhone. So North Korea is essentially a black hole.
