iOS 5.1 coming as Gold Master is said to have passed QA test5
Some of the new features expected for iOS 5.1 include Japanese support for voice activated/personal assistant Siri, a new permanent camera icon for the lockscreen that sends you lickety split to the camera app, and a possible update to the Notes app to name a few. The latter would replace the drab note-taking application with a variety of colored backgrounds/text and a number of new fonts to choose from.
Now that the software has passed the QA test, it should soon be ready for the end user. As for when that will be, a month ago we showed you a profile that hinted at a March 9th release of iOS 5.1. Besides the Japanese fluent Siri, the newest build of Apple's mobile OS should also include a fix that should end any issues that Apple iPhone 4S users are having with the battery.
