The day that Sony Ericsson Xperia X10 owners in the US have been waiting for and perhaps even praying for as there were many times when we didn’t think this day would come at all for the x10, has arrived – Gingerbread aka Android version 2.3 is here!

Gingerbread for the Xperia X10 brings the Facebook inside Xperia feature which basically integrates Facebook into your handset, USB tethering, app tray sorting and the ability to use the X10 as a portable WiFi hotspot, amongst other features.

After months of waiting, the Android 2.1 update has finally been released in the US for AT&T branded handsets. The update was initially released October 31st and information followed shortly saying that because of rigorous testing from AT&T, the update could be months away and months away it was. After 7 months after the initial Android 2.1 release, Sony Ericsson are close to releasing an Android 2.3 update for the handset.

Users are reporting that a new update for the Xperia X10 has been released. The update brings the build number up to 2.1.B.0.1 which was certified on the PTCRB site on May 24th. The baseband version has also changed to 2.1.67.

There isn’t much information on what the update does but, users are reporting an improvement in battery life, as well as over all performance.

It appears that the Android Market has been updated on Xperia handsets which adds a link to Sony Ericsson apps. The update doesn’t actually appear to be a market update however, as there wasn’t a notification and uninstalling any Market updates, does not revert the Market to how it was.

When Sony Ericsson announced that they would not be upgrading the Xperia X10 past Android 2.1, this left a lot of users very angry and caused many to swear they’d never go back to Sony Ericsson. In light of this, Sony Ericsson have listened to the feedback and have today confirmed that the Xperia X10 will be updated past Android 2.1.
