Security experts are urging iPhone users to upgrade to the latest version of its operating system, after it was revealed that it included patches to over 40 security vulnerabilities.
Apple released the iPhone 3.0 software update on Wednesday, free of charge to iPhone users and around £6 for iPod Touch users. But according to an advisory on the official site, the new version of the OS patches 46 vulnerabilities.
Sophos senior technology consultant Graham Cluley wrote on his blog that some of the vulnerabilities could enable hackers to run malicious code on a user's iPhone, if that user visited an infected web site.
"Fortunately we haven't come across any examples of hackers creating malware to exploit these vulnerabilities so far," he added.
Cluley also argued that it was unusual for Apple to be charging some of its customers to receive important security patches.
"In an ideal world Apple would make free fixes available for iPod Touch users who don't feel they need cut-and-paste and other new features, but do want to be able to use the internet securely," he said.
