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.
As it stands at the moment, the update can’t be performed as an OTA (over the air) update. Instead users will need to use the Sony Ericsson Update Service or PC Companion to update the firmware version. The download totals 153.8MB.
