They say that people are getting mugged for their cordless *smart*-phones in cities.
They are also likely to be targeted by thieves in a smartphone crime wave fuelled by the enormous appetite for the machines that serve as status symbols, essential worktools and mobile entertainment centres.

In Britain, a 30-strong National Mobile Phone Crime Unit is battling what a police spokesman said is "a general increase in the proportion of thefts which involve smartphones."
Susana Ramirez, a 29-year-old author and newspaper columnist in the Spanish city Barcelona, told AFP that a blog she wrote about her fear of using her iPhone in public sparked a huge response from her readers.
"I look to the right and to the left before I get out my phone," she wrote in the blog. "As if, instead of a phone, I was about to take out a knife or a stash of drugs on the street."
In New York, public announcements warn subway commuters not to display phones or other electronic devices.

Read a book on the train. Or carry a notebook and WRITE something, anything(!), down - that's what I do.
