Sony Ericsson recently released a new update for their 2011 range of handsets. Unfortunately, the update for the Xperia Play, was not released at the same time as the update for the Xperia Arc and Xperia Neo.

Xperia Arc owners in India can now update their handsets to run Android operating system version 2.3.3, according to androidos.in.

Currently running on Android 2.3 aka gingerbread, the Arc update brings the 2.3.3 feature “Facebook inside Xperia” along with other tweaks to the touch responsiveness and battery life along with software enhancement to hopefully make the Arc smoother to use.

The update is initially available via the Sony Ericsson PC Companion suite for Indian customers.

O2 UK have finally released the latest update for the Xperia X10. O2 were the last network in the UK to approve the update, causing many O2 customers and Xperia X10 owners much anger. The software update has gone straight to R2BA026, where as initially it was thought that the older, R2BA020 firmware would be released. The latest update is said to improve the battery life, with many owners agreeing. X10 owners with the latest update are also reporting that the overall performance is much better and especially in TimeScape and MediaScape. Unfortunately, the latest update also includes the WiFi bug. The only firmware users didn’t find this a problem, was in R2BA020, so I’m sure there will be some users who wished it was the earlier firmware released onto O2.

Sony Ericsson have released another firmware update for the Sony Ericsson Xperia X10, bringing the build number up to R2BA026. It’s recommended however that you don’t install the update if prompted as it brings back a mysterious WiFi problem which we haven’t seen since R2BA016. The issue occurs when you lose the network signal on the phone. Upon losing (and regaining) signal, the Wifi turns itself off, so you lose all connections to the internet, making the phone brick like for a few minutes until the signal returns completely. As well as bringing the Wifi issue back, the update sees the Wise Pilot app taken off. The only improvement in the firmware, is that Timescape and Mediascape are more responsive.

The Xperia X10′s system firmware has been updated from R1FA016 to R1FB001, and has also had update for the baseband to 1.0.21. There have been reports of dramatically improved system performance, especially with both TimeScape and MediaScape. Run the Sony Ericsson Update Service to update your X10′s firmware, and you’re done. However, currently the updates seem to only be available on the American and Nordic models, but will inevitably become available for all models within the coming days. Additionally, expect to see another update toward the end of the month specifically designed to solve the X10 battery issues.
