The cellular telephone that went off with a "Boomer Sooner" ring tone got the attention of one Norman church congregation recently. But when the woman took the call and began chatting away while others prayed, heads began shaking.

Churches used to be one of the last cell-free refuges these days. Some businesses are trying to be but find the going tough as customers want to be able to multi-task while they shop, check out, dine, golf, go to school, exercise or generally go about daily business.

An estimated 202 million cell phones are in use,?up from 28 million in June of 2005, according to USA Today newspaper. A survey cited by the newspaper said Americans think it's acceptable to talk on a wireless telephone in a bathroom, car, supermarket and public transit but not in a movie theater or restaurant.

The newspaper, in a story this week, describes a Texas dentist's office that went cell free after patients were mired in conversation while getting their mouths X-rayed.

A growing number of states and businesses are cracking down on unwanted cellular traffic. Many fine dining restaurants have established cellular zones, much like smoking areas.

Legislation restricting cell phone use -- mostly by drivers -- has been introduced in 39 states this year. No state bans all cell phone use in cars. Ten states ban their use by teen drivers who have only a permit, not a license.
