Xperia X10 users around the world are reporting that they have begun receiving the R2BA026 firmware. As always, this update can be downloaded through Sony Ericsson Update Service (SEUS). Regions which have been confirmed to have already received the firmware update include UK, India, Canada and Australia.
Since, Sony Ericsson doesn’t provide change logs, it’s hard to pinpoint exactly what has changed. However, several users are reporting significant performance improvements. In particular, Timescape and Mediascape apps appear to be a lot more responsive.
