When I saw title of this topic I was like. Wow, another topic how bitcoin is great and how can you send money across the world with no problems now.
But after reading every post here I am now little sad. People here are just  too optimistic over bitcoin in my opinion. Bitcoin is not good choice when you have no electronic infrastructure to back it up - then bitcoin is borderline useless. To sum this story up: You can't do anything with just smartphone with shitton of bitcoin on it. No when there isn't any bitcoin service :/ Sad really.
