iPhone Security - Risks and Dangers of Mobile Communications
Because of the current structure of the mobile communications system, smartphones have become significantly more vulnerable to "cellular hacks" compared to other computer devices. The two major concerns when it comes to mobile communications are eavesdropping and automatic rebilling. On analog networks such as CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications), anyone within your range with a scanner could pick up your cellular signal and listen to every single one of your personal and private conversations. With the recent move towards CDMA and GSM digital networks, your phone calls are now encrypted for your protection, however, eavesdroppers with the right patience and determination can decrypt your calls and still listen to your conversation.
