Vodafone customers can now download the Android 2.3.3 update for the Xperia Play and Xperia Arc. Sony Ericsson started a global rollout of the firmware patch at the end of last week, and the network provider has been pretty quick to respond.

The new patch offers several improvements to the operating system, including improved voice quality, better device stability, improvements to email setup and performance with exchange accounts, and security fixes and enhancements.

It can be downloaded and installed by attaching your Xperia Play or Arc to your computer via USB and opening the Sony Ericsson Update Service application. It should prompt that an update is available and then follow the onscreen instructions.

Vodafone also suggests that owners can check which version of the software they have on their handsets by dialing *#*#7378423#*#* and then navigating to Service info, then Software info. The new software version will show as 3.0.1.A.0.145.
