All updated (ota notidication wnhich thnen asked me to do via updater software on pc) and running fine. Noticably smoother all round, not noticed much else other than the 'no saved connections' bug but that's a minor really..

I did have a minor scare after installing the power kernel and then the screen would freeze for a couple of seconds at regular intervals. Ljuckily I tried resetting before i attempted to uninstall and now t seems to be working fine..
