Hello. I have a friend. With an iPhone 4S, it's totally dead. I would try to do a hard reset to get it going, but the home button is missing. What an I do from here. Kinda stuck in a bad situation. She never backed up her phone so. She said this had happen before in the cold and after leaving it for a few days it turned back on. No dead battery symbol. The one day while texting. Her phone died again. It did turn back on eventually. Now it's completely dead. Can't do a hard reset. So kinda stuck. And doesn't do anything when plugged in to a charger Any ideas on what I can do?
