The rabbis in Israel have told followers to scorn television and radio. But mobile phones are considered essential in one of the world's most tech-friendly nations. In 2004, a special rabbinical panel was formed to study how to bridge the need for cellular phones and religious codes. Some believed the sophisticated "third generation" phones offered an unhealthy freedom: the ability to download pornography or allow young people to make furtive contact with the opposite sex - which is highly restricted in ultra-Orthodox society.
在世界上對科技最友善的國家之一以色列，猶太教士告訴教徒要擯棄電視和收音機，但是手機被認為是必要的。二○○四年成立的猶太教士特別小組，研究如何溝通手機的需求與教規。有些人認為精密的「第三代」手機提供有害健康的自由：可下載色情，或允許年輕人偷偷摸摸與異性接觸（這在猶太教超正統派社會是強烈制止的）。

The kosher phone that debuted last year by Mirs Communications Ltd., an Israeli subsidiary of Motorola Inc. is stripped down to its original function: making and receiving calls. There's no text messaging, no Internet access, no video options, no camera. More than 10,000 numbers for phone sex, dating services and so forth are blocked. The phones - carrying the seal of approval from rabbinical authorities- have been one of the most successful mergers of technology and centuries - old tradition in the ultra-Orthodox community.
摩托羅拉附屬的以色列Mirs電訊公司，去年推出的清淨手機已削減到初期的功能：撥出和接聽電話，沒有簡訊、不能上網、沒有錄影選擇、沒有相機。一萬多個性愛電話、約會服務等被阻斷。這款手機蓋有猶太教當局的核准章，是科技與幾世紀猶太教超正統派傳統最成功的結合之一。

More than 20,000 kosher phones were sold. But it was just a foothold in an estimated market of at least 180,000 cell phone users among Israel's nearly 1 million ultra-Orthodox. Mirs is under way to promote a kosher phone to Jewish communities in the United States and other nations. Israeli Arabs have also taken notice of the phones as a possible option for those trying to protect conservative Islamic sensibilities. .
清淨手機已賣出二萬多支，這個銷售量只是一個據點而已。在以色列將近一百萬猶太教超正統派教徒中，預估市場至少有十八萬名手機使用者。Mirs正進行將清淨手機推廣到美國和其它國家的猶太社區。以色列的阿拉伯人也注意到，這款手機可能成為想維護保守伊斯蘭教意識者的一項選擇。
