1) Do not flash any other kernel with this; there are no compatible ones as of now.
2) This will NOT wipe your internal storage; all your media files and things on /sdcard are secure!
3) There are random lockups bringing you to the lockscreen; you have to unlock again.
4) In case you missed it: I am the official Ubuntu Touch developer responsible for the Xperia S. Intel: https://wiki.ubuntu.com/Touch/Devices/nozomi
Well, if you want anyone else than me to be the official developer of UTouch for the Nozomi, I'll happily let someone take over the project and offer my help and sources. But I have to make sure he is qualified for this first.
I just have absolutely zero time at the moment, and I am rather concentrating on OpenSEMC.
