Recently I realized that having my iphone wake me up was much easier if it were next to me on my window sill. I realize that having a phone next to me while sleeping is probably detrimental to my health so I was wondering if I put my phone in airplane mode, does the alarm still go off? And more importantly, if I get a text message while in airplane mode, does it get delivered as soon as I take it out? I wouldnt want to miss any texts.
