Although most Android OS v2.3.4 are scheduled to be released in October, some seem to have been blessed more than others. Sony for example, has decided they want to surprise everybody and release it a bit sooner than announced.
The first one to benefit from this generosity is the Xperia NEO (others will be getting it soon as well). The update brings the firmware version from 4.0.A.2.368 to 4.0.1.A.0.283.
Along with adding Android specific updates such as the ability to make video calls from Google Talk, the Xperia NEO will also get features like 3D Sweep Panorama, swipe-based text input, built-in screen capture function and enhancements to the Facebook integration.
If looking at it from afar, you notice somethings are similar to the future announced Xperia NEO V and the Xperia Arc S.
All and all, it is a good day for Android OS lovers.
