X10 更新? ， 但是好像沒升級os2.1?

Home Screen and HD video in the X10 Update
Now I’ve shot some videos of the pre-release software update that I have in my XPERIA X10. This is not the final release but we are really close to releasing the final candidates into external and operator testing and approval now. When that testing is ready and the candidates gets approved the roll-out will start. The current plan still holds to start the roll-out towards the end of October and onwards. (As mentioned earlier the roll-out is done gradually though so it will take some time before all different versions get the update.)
In these videos I try to show you both what the updated home screen looks like and also some results from HD video recording with continuous auto focus.
Remember that even though we are close to a final candidate this still is pre-release software so there might still be small changes and optimizations made before commercial release.
First video out is a short clip showing the home screen that now has 5 panes and some other nice additions such as 5 rows of icons instead of 4. I also show some new widgets that come with the update.
