To some of you this is old news, but to the rest, its brilliant news. The Gingerbread update (2.3.3) update started rolling out to certain devices on Friday and they hope to have it finished this coming Friday.
As far as what it contains, here is a snippet from the Sony Ericsson Product Blog.
As said in March most of the 2011 XperiaTM software functionality from e.g. XperiaTM arc will be included. The UI with the desktop layout and pinch-to-overview gesture will be similar and Gingerbread features like Wi-Fi & USB tethering, App storage on SD-card etc are included. Also the customizable horizontal app tray and the media experience widgets from the 2011 XperiaTM Products are in, including an integrated equalizer in the music player. Of course also apps that require Android versions 2.2 or 2.3 will now be possible to download from Android Market, e.g. Adobe flash.
One difference compared to the 2011 products is that DLNA will not be included. Extra type approvals were needed for that and we were unable to prioritize that without jeopardizing the time schedule. There are both server and client alternatives downloadable from Android market though.
