iPhone expert Charlie Miller - who was able to control an iPhone two years ago with malformed code on a website - claims to have teamed up with fellow expert Collin Mulliner to highlight a text messaging flaw on the popular Apple mobile.

If true, then the flaw allows a hacker to gain remote access to an iPhone using a humble text message.

Reports suggest that the hack requires no input other than viewing the text message from the user, who simply sees a block character on his/her display, at which point the iPhone is under the control of the remote hacker.

The researchers claim to have alerted Apple to the problem several months ago, but Apple has not patched the alleged security flaw.

Infosecurity suspects that the security flaw will be patched rather quickly now.
