Just curious how everyone feels about this. Regarding notification sounds - do you have yours turned off so that they don't interrupt you while you're on a phone call? Here's my dilemma. I want to hear all of my notification sounds - but I don't want to hear them while I'm on a phone call. I realize that you can't have it both ways - you tell the phone to make a sound and it makes the sound. I just wish iPhone was smart enough to sense when you're on a phone call and temporarily "suspend" the notification sounds until you're off. Does anyone else have the same frustration? With everything that's so awesome about iPhone and iOS 5, you'd think this would be common sense ...? Is this an unreasonable expectation?
