CNN mid-morning anchor Carol Costello was mugged of her iPhone on the streets of Atlanta.

She wrote about it on her Facebook page:

Good Morning. In retrospect, what happened to me yesterday is insignificant in light of what happened in the Boston.
Still, I feel the need to vent. And isn't that what friends are for?
I was robbed.
And I am angry.
I was walking down a beautiful, leafy Atlanta street, talking on my IPhone.
Guess what happened next?
Three teenagers ran up behind me. One of them grabbed my IPhone. Stupidly I struggled to hold on-to it. But, he was a big guy. And he pulled out a chunk my hair.
I let go.
As he ran down the street, laughing, I hurled a few expletives his way.
I felt no fear at the time, I was just angry. Now I'm angry, shaken and sad. What a lousy life those kids have ahead of them.

As smartphones proliferate, they have become easy items to steal and resell. The New York Times recently ran a page one story about the subject and how manufacturers don't seem to be doing much about it.

Her advice: don't talk on your smartphone while walking down a public street because you're a ripe target for a mugging.
