New iPhone 3GS Security Flaw Exposed

It's not the first iPhone security vulnerability uncovered but it's reasonably serious and Apple has yet to respond with a timeline for correcting it.

"Using a four-digit PIN to lock your iPhone doesn't really protect your data, security and IT blogger Bernd Marienfeldt has discovered. In an article describing the iPhone's business security framework, Marienfeldt has found a "data protection vulnerability" in Apple's iPhone 3GS.

Marienfeldt, working with security expert Jim Herbeck, has been able to reproduce the vulnerability on at least three non jail-broken iPhone 3GS handsets with different iPhone OS versions installed (including the latest). All tested iPhones were protected with a four-digit PIN."
