Along with the Xperia Arc and Play, Sony Ericsson has started rolling out a new firmware update for the older generation Xperia branded handsets the X10. Apparently, the update is also being rolled out to the Xperia X10 Mini, Mini Pro and the X8.

The new firmware update does not bring any major changes, and nor is it the anticipated Android 2.3 update for the X10. The update is basically aimed at improving the general system performance and stability.

X10 users over at XDA who have updated their phone to the latest firmware (2.1.B.0.1) report performance improvements, smoother operation, and improvements in camera image quality as well. The Timescape app is also much smoother now. The firmware update also includes a new baseband, so users should expect an increase in network reception along with higher data transfer speeds.

The new firmware is also root able, so users don’t need to worry about losing root access to the system partitions. At the moment, the firmware update is being rolled out only in Germany. Expect this firmware update to roll out in more regions of the world beginning from tomorrow.
