I've seen a few people ask about this, but no one seems to have an answer yet. I'm trying to turn off the wifi to save battery. I have turned it off with both the widget and in the settings. After I turn it off, the next time I unlock the phone to do something, the wifi turns itself back on! I can't keep it turned off. Does anyone know why or how to stop this? And no, it's not a "feature", you must be able to turn off the wifi somehow.
