What do NYC teens do with their cell phones during school during school hours?

In the article, "'May I have your attention?' The consequences of anytime, anywhere technology" I learned that in the NYC public school system, as of 2006, students' cell phones were confiscated at the doors along with knives, razor blades, and marijuana. At my high school we could bring cell phones, iPods, and laptops to school--as long as they stayed stowed away in our lockers and weren't brought to class. I wanted to find out how New York students were dealing with the confiscations, if they were still happening. What did they do after school, when they needed their cell phones to coordinate rides home, picking up siblings, and group projects?

According to an article I found from 2012, this is how: Cell phone "valets" with storage trucks park a short distance away from the school and charge students a small fee to safely store their phones during school hours. Students pay up to $180 a year for this service. It's a lot of money, but perhaps a better option than paying a $15 fine and having their parents come to school to every time their phones are confiscated.
