If you would like see what problems people face on their mobile phone (to test whether it's user error or system error and help to reproduce things locally to fix) you might want to look at Splashtop.com/SOS. It enables developers/testers to see what's happening on someone's mobile phone as they are using it. We use it when we want to check what some of our app users are doing to cock things up so badly It works across iOS and Android.
