Up until now Sony Xperia S users with locked bootloaders have had no way to get root access. Many mobile operators such as O2 or T-Mobile in the UK ship the Xperia S with locked bootloaders. This has left many people frustrated that they cannot remove bloatware via root access. The good news is that root is now available for those who have a Sony Xperia S handset with locked bootloaders.
The process posted by Sharaz22 over at xda-developers is reasonably lengthy and also a bit complicated. To implement root, your handset will need to start off with stock Gingerbread firmware. An exploit is then opened at which point you need to upgrade to ICS to actually activate the exploit. The process only works in ICS and you MUST start the process from Gingerbread. A number of people are reporting success, so if you have been dying to get root on your Xperia S you can find the full instructions here.
