A second worm to hit the iPhone has been unearthed by security company F-Secure.

It is specifically targetting people in the Netherlands who are using their iPhones for internet banking with Dutch online bank ING Direct.

It redirects the bank's customers to a look-a-like site with a log-in screen.

The worm attacks "jail-broken" phones - a modification which enables the user to run non-Apple approved software on their handset.
