I thought I read the feature they were adding was that you could toggle it so wifi never went to sleep, or hibernate, whatever they call it, so that IM apps and texting apps on a Touch could stay active. I'm seeing what I think is the Wifi on all the time, and I'm now getting alerts from Beejive when someone texts me, but I see no setting anywhere to turn this off. Is it simply on with no option to turn it off?
