I'm presuming. Personally, even if it's just an ROM update, I wipe the 'big 3' every time. Too many issues are caused by people trying to cut corners and not wipe data. For me to get back to where I was before wiping, it literally takes maybe 15 minutes with tibu and a settings restore with GoLauncher and Go SMS.
Cheers to you Naven!! Downloading now but I have to wait to flash at work tomorrow morning.
Either way im gonna big 3 wipe as u called it as I don't mind setting my.phone all over again. Always good practice
