The new Android 4.0.4 update has been rolled out for Xperia Sola, Xperia Go, Xperia U and Xperia P by Sony Mobile which brings in a couple of bug fixes as well as a lot of performance improvements.
According to a Sony Blog report, the update based on Ice Cream Sandwich (ICS) firmware will encompass improvements to WiFi, stability, camera (both capture and playback), Messaging, NFC and portable or tethering hotspot. The ICS update had been rolled out by Sony for Xperia P back in August. Xperia Sola, Xperia U and Xperia G got the ICS update from September onwards this year.
Xperia P users would be getting the update Over The Air (OTA). They can also update using PC Companion or Windows or via Bridge for Mac which can vary from region to region and also carriers.
