Apple has released the iOS 4.3.1 update which deals with certain graphics and mobile connectivity issues as well as provding some minor enhancements.
The minor security and performance update was released to coincide with the launch of the iPad 2 in 25 countries including the UK. Apple released the update a week or so earlier than many had expected. The update brings security and performance enhancements to Apple's iPhone 4, iPad, iPhone 3GS and the iPod Touch.
According to the company, the update fixes a graphics glitch found on the fourth generation iPod Touch, patches several bugs related to activating and connecting to some cellular networks, fixes an issue with the Apple Digital AV Adapter that caused images to flicker and fixes bugs that caused problems while authenticating some enterprise web services.
There had been some reports that the software would improve the iPhone's battery life, though this is yet to be confirmed.
It is still not clear whether the update fixes vulnerabilities that were being exploited by developers to jailbreak iOS devices. Apple would also would not confirm if the issue fixes a critical bug in the Safari browser that was discovered and exploited in the Pwn2Own hacking contest.
