Thanks for the reply. I don't know if I have that installed, though I remember seeing references to it flash by. It's probably getting a bit involved now (I've uninstalled so many things, and run QTweak so many times I can't remember exactly what I've done, and am a bit tired of it all). I'll just keep things they way they are I think. Everything I want is working except flight mode, which is easy to access via Settings anyway, so no biggie
