Ever worry that someone is trying to spoof the origin of text messages on your iPhone? Well according to developer pod2g you should. Although the security flaw he cites is not capable of executing malicious code, it can be exploited to fake the origin of an SMS to an unsuspecting iPhone user.
Pod2g is hoping Apple fixes the problem before the final release of iOS 6. If iOS dealt with incoming text message information properly, the message would display the reply-to (spoofed) phone number as well as the actual originating phone number. As currently configured, iOS only shows the reply-to number.
