Apple has just introduced iOS 4.3.5, a version of this operating system that has patched a small security flaw. This is the latest in string of iPhone system software updates to fix bugs and close security holes.
The official change log for this new version says simply "Fixes a security vulnerability with certificate validation." Apple's support website goes into more detail on the problem being dealt with: "An attacker with a privileged network position may capture or modify data in sessions protected by SSL/TLS".
Installing this update requires hooking a recent-generation iPhone, iPod touch, or iPad to a PC with iTunes installed on it. The new version will take several minutes to install.
There is an identical update released today for Verizon's version of the iPhone 4: iOS 4.2.10. The installation process for this is the same.
The Latest Of Many
Users of Apple's mobile devices should be getting used to installing small updates. Since iOS 4.3 launched in February, there have been four small updates released, all "bug fix" patches.
iOS 4.3.1 came out just a few weeks later and fixed a number of glitches. It took another couple of weeks for Apple to come out with iOS 4.3.2, which fixed just a single bug, a video problem with FaceTime. In May, the company came out with iOS 4.3.3, which removed the notorious tracking bug that caused many to think their iPhone was spying on them.
Just ten days ago, Apple came out with iOS 4.3.4, which took care of a security problem related to PDF files. And today there's iOS 4.3.5.
It's not known yet whether this will be the last such update before the debut of iOS 5, which is expected to happen in early fall.
