Ice cream sandwhich update on sony ericssonlive with walkman

ICS update is already released. You might want to know, what you need to do to get the update. Make sure, that you have a working Xperia 2011 device with stock ROM and stock kernel installed(if you install via PC Companion or SEUS) and locked bootloader(if you install via PC Companion or SEUS). 

Root access doesn't matter(according to current information),whether you have or not. It is lost after update anyway. PC Companion and/or Update Service installed on your computer. Drivers working for your phone. Official update will only be available via PC Companion and Update Service. But you can also use Flashtool to install ICS.
