A yet-unannounced Android 2.3.4 Gingerbread update for the Sony Ericsson Xperia play has been rolling out to several users, and it comes with a really nice surprise: 720p HD video recording capability (with continuous autofocus) for the Xperia play.

Several members of XDA Forums have confirmed receiving the update for their Xperia play. One member also posted a sample video taken using the Sony Ericsson Xperia play running updated Gingerbread.

The update apparently is not yet being delivered over-the-air (OTA), although some forum members say it will eventually be pushed out as an OTA update. There was also mention of the update’s availability through PC Companion.

The Sony Ericsson Xperia play is an Android smartphone intended for those who wish to use their smartphones for video gaming. It has a slide-out game control pad with controller buttons and two touch-sensitive analog sticks.

The HD video recording capability enabled by the Android 2.3.4 Gingerbread update practically extends the Sony Ericsson Xperia play’s functions beyond just smartphone and game console in that of HD video recording device.

For a sample of an HD video recorded using the Xperia play, take a look at this video provided by one XDA Forums member:
