Sony Ericsson Xperia X10 users on the airwaves of wireless carrier O2 UK have now a reason to rejoice, as the company has just announced the availability of the Android 2.1 software update for their devices.

The operating system upgrade was originally expected to arrive on Sony Ericsson Xperia X10 devices at O2 in the beginning of this week, but it seems that the company has actually delayed the launch a few days more.

In all fairness, this was not the first delay that the Android 2.1 OS upgrade for Xperia X10 devices, X10 mini and X10 mini pro included, registered.

Initially, Sony Ericsson announced that the software update will be released sometime in September, but it had to delay the solution a few times.

However, the roll-out of this upgrade started at the end of October, and continued for many unlocked devices out there, though carrier branded Xperia X10 units started to receive it a little later.

Starting today, O2 UK customers who own an Xperia X10 smartphone have the possibility to upgrade their handsets to a news flavor of Google's mobile OS, after being stuck to Android 1.6 for the past several months.

According to the wireless carrier, the Android 2.1 software should become “fully available” this afternoon, though there's no telling how long it would take for all Xperia X10 users out there to update their handsets.

“The Sony Ericsson Xperia X10 2.1 update is available today. It's starting to roll out and will be fully available from this afternoon,” the wireless carrier announced via its Twitter account.

Following the update, users should benefit from a nice range of enhancements on their devices, including access to more applications and services.

According to Sony Ericsson, some of the main improvements include: Xperia X10: • HD video recording with continuous auto-focus for high quality videos • Upgrade of the Android platform to Android 2.1 • New backup and restore application, with extended content back up • 5 homescreens for apps, widgets, shortcuts and folders • Social phonebook which automatically syncs contact pictures from Facebook and shows when your friends are online

Xperia X10 mini and X10 mini pro: • Improved Bluetooth functionality with support for sending and receiving pictures, contacts and more • New backup and restore application with extended content back up • Automatic synchronization of your contact pictures between Facebook and your phone book • Improved ways of handling pictures, audio, text and numbers in your messages • Upgrade of the Android platform to Android platform 2.1
