Your GSM cell phone conversations are not secure

A security researcher has unveiled a decrypting method for phones that use the Global System for Mobile Communications (GSM). This means that if you are using a GSM cell phone, it has just gotten easier for someone with the right tools to eavesdrop on your calls.

GSM is the most widely used mobile phone protocol, with about 80% of all mobile phones using it worldwide. It is the de facto standard in most networks in Europe and Asia. Some of the well-known networks providing GSM phones in the USA are AT&T and T-Mobile. Verizon Wireless and Sprint uses a different protocol, called CDMA, that was originally developed by the U.S. military.
