Sony Ericsson's Xperia X10 may be more than a year old, but the ol' girl is still good to go, thanks to a fresh new software update in the form of Android 2.3

The Xperia X10 was introduced in March 2010, boasting the even-then-outdated Android 1.6. However, with the update of Google's latest version of the smartphone operating system, Sony Ericsson appears to be looking to spark a little more life into the smartphone.

The update includes a number of new features, such as USB tethering, Wi-Fi hotspot capabilities and the addition of an equalizer to the music player. Additionally, Android 2.3 improves the smartphone's Facebook integration by incorporating the social network with the user's phonebook, calendar and multimedia apps.

The update is available now for carrier-free models of the Xperia X10, and will be pushed out over the air to other models soon. However, Sony Ericsson has not yet established a schedule as to when the OTA update will be available.

Sony Ericsson hasn't made much noise in the smartphone market lately, especially compared to some of its competitors. However, earlier this year, the company did make a splash by introducing the Xperia Play, an Android-based smartphone that doubles as a handheld gaming device.
