Last week, prominent computer-security researchers Charlie Miller and Collin Mulliner demonstrated an iPhone vulnerability that could allow a hacker to gain complete control over all iPhone functions, including making calls, visiting websites, accessing personal information on devices, and turning on the camera and microphone. The hack could be executed through a series of hundreds of invisible text messages, which would embed code into system's memory and run a malicious executable file. The user would only see a single message containing a small square. Once one phone was compromised, it could be used to send the same invisible text messages to other iPhones.

In response, Apple has released a free patch that repairs the vulnerability. To download the software update, go to iTunes, choose your device and click "Check for Update." A dialogue box should tell you that version 3.0.1 is available for your iPhone. Go ahead and click "Download and Install," and follow the commands from there.

Researchers also announced that they have found a similar vulnerability impacting Windows Mobile devices. Microsoft is currently investigating the claim.

As smartphones evolve to become more and more like personal computers, they also become more vulnerable to these types of threats. It is important to be aware of this danger. Soon enough, Internet security software for phones will be available and necessary. For now, the best way to protect your phone is to be aware of the latest threats and software upgrades and refrain from clicking on unknown links or downloads while using your smartphone.
