Chief among the listed updates that come with the newest Apple operating system is one that "fixes bugs affecting battery life." The poor battery life on the iPhone 4S (and other Apple devices running iOS 5) caused a minor tempest on tech sites and on the Apple forums; on November 2, Apple confirmed that the battery drain was being caused by a problem with iOS 5 and not with the hardware itself and that it was working on a fix.
Other updates coming with iOS 5.0.1 include multi-tasking gestures for the first-generation iPad, a fix for a bug that was affecting documents in iCloud and better Siri voice recognition for Australians.
You can download the new iOS 5.0.1 for iPhone, iPad and iPod Touch by connecting your device to your computer and opening up iTunes.
