It’s been a while since Sony Ericsson announced the non-Eclair upgrade for their Xperia X10 users – said to considerably improve battery life and bring about better performance – but O2’s finally ready to deliver it to their customers. It’s Firmware R2BA020 – the same build with the WiFi bug – but perhaps it’s a small price to pay if you felt the phone was starting to get sluggish and if you were frustrated with battery life.

You can’t receive the upgrade over-the-air, but you can download it using Sony Ericsson’s PC Companion tool. The file clocks in at 153.8MB in size.
