Ok, dumb question here...
I just put kies on my laptop, plugged the phone in, and it did loads of updates and whatnot. So how do I know if I'm now on this Ice Cream Sandwich thing? Love the name of it, by the way.
Also, have just been through most of this thread and downloaded Elixir, Lookout and JuiceDefender as per your recommendations - so thanks for that.
