Wireless World: Religious ringtones

The muezzin is calling. But the cleric is not in a minaret, above the town square, reminding all that it is time to face Mecca and pray. He's a digital muezzin, calling on the mobile phone of the worldwide faithful, with a daily reminder ringtone. Experts are telling United Press International's Wireless World that religious ringtones -- and ringback tones -- are growing in popularity throughout the world amongst people of faith.
