e says he says he's seen a lot people toting around cell phones, but he believes many people have bad manners when it comes to using their phones in public. People who use their phones while driving or leave their ringers on at concerts particularly annoy Reemsnyder.

The basic rule that etiquette books, newspaper columns and cellular phone company new user pamphlets agree about is that people should refrain from having conversations and turn their ringers off when are at a place where it would be rude to make noise, with or without a cell phone. These places include classrooms, public performances (concerts and plays), movie theaters, church services (including weddings and funerals) and the library. Cell phone use in low noise areas, such as in restaurants and on public transportation, are also considered to be rude.

So far, cell phones in the classroom haven't been enough of a problem for the university to form any policy on the mobile devices. Individual colleges and departments haven't made any special rules about them, either.

Vance Hill, freshman fashion design major, talks with a friend outside of the library.

Catherine Bakes, coordinator for the mathematics and computer science department, said students tend to turn off their phones or their ringers and avoid holding conversations while class is in session.

"I've had very few interruptions. Students are usually pretty polite," she says. "But if it becomes a problem, we have to address it."

But some professors have had enough problems with cellular phones that they have noted their own policies on their syllabi, warning students on their first day of class that phone interruptions will not be tolerated.
