hi, is it possible to disable the signal? What I mean is that when I take the metro, there so signal, cuz the metro is underground. So to save battery I turn off the phone but is getting tired to do it repeatly cuz i don't want to turn off the phone and turn it back for 2 to 4 time per day, cuz I often travel to go place for work. So I was wondering if there any function so it doesn't allow any incomming or outgoing signal, like someway to save the battery without turning off the phone?
thanks
