A North Korean guide uses a pointer at the start of a tour of an historic site. On Jan. 18, 2013, foreigners were allowed for the first time to bring mobile phones into North Korea. And this week the local service provider, Koryolink, is allowing foreigners to access the Internet on a data capable 3G connection on our mobile phones. In the past I could post geolocated phone photos to my Instagram feed by turning my online laptop into a hotspot to link my iPhone or iPod touch by wifi. But, today I'm posting this directly from my phone while riding in the back of a van in #Pyongyang. The window on to North Korea has opened another crack. Meanwhile, for Koreans here who will not have access to the same service, the window remains shut.
