I have an iPhone 4s running iOS 5.1. I use the reminders app for tons of stuff, including keeping a grocery list. That grocery list is shared with my wife so we can both see and update it on our iPhones. Since I upgraded to iOS 5.1, everytime that she adds an item to the list I get an e-mail telling me that it was added. This is very annoying and am wondering why it is doing that and how to stop it. Thanks
