lost iphone

It seems there was a transfer of wealth, my phone was lifted by someone slick from someone slow. Not to be found, the find my iphone app didn't work so I guess they took out the sim card, I have to get a lanyard and put it around my neck, better yet keep it in a zippered pocket, one of the things that I don' like abotu the city is the bike thieves and their ilk, I have about 60 pounds of locks on my bike. In Chiang Mai, My wallet fell out of my pocket and 3 young people came up on their bike and gave it to me. I had a thousand dollars in it, they would not take a reward. different cultures I guess.
