iPhone-4

It seems there is a flaw in the way that Apple implements the SMS protocol on their phones. As most know there is no such thing as secure communication when you are transmitting data back and forth over the internet. There are methods that are more secure than others, but nothing is “secure”. This holds true for the PDU protocol (Protocol Description Unit which covers SMS) which has multiple pieces, standards and even methods for transfer. Because of the complex nature of this standard it is in the hand of the phone developer and the carrier to make sure the implementation is done correctly.
