Sony Mobile has updated their What’s New application to build number 3.4.A.0.5. So this will replace the previous build 3.4.A.0.4. The primary new feature of this new update is the ability to disable notifications within the settings menu. Whats New app gives us notifications rarely. So personally they are not annoying for me, but it may be an issue for some. As usual there are performance improvements and UI enhancements.
