From the iht.com, I read this article and it is hilariously cute!
"When Larry Pinczower switches on his cellphone, the seal of a rabbinate council appears. Unable to send text messages, take photographs or connect to the Internet, his phone is a religiously approved adaptation to modernity by the ultra-Orthodox sector of Israeli life.
More than 10,000 numbers for phone sex, dating services and the like are blocked, and rabbinical overseers ensure that the lists are up to date. Calls to other kosher phones are less than 2 cents a minute, compared with 9.5 cents for normal phones. But on the Sabbath any call costs $2.44 a minute, a steep religious penalty."
