My sister has a 3g. She has it set to open the camera when you double tap the home button. When she does that nothing happens. So she tried to go to the camera app to launch it that way and it is gone. She has 3.1 installed. She did that earlier this week and her camera was working fine. We are trying to update to 3.1.2 right now but it is saying it will take 24min. Anyone else have this problem or have an idea what to do? She has had the phone for a month. 3.1.2 didn't fix anything.
