Sorry for the inconvenience. Can you log into web using Sprint Network. If yes, I would suggest you to powercycle your phone and update profile and then download Sprint ID. Also make sure that you turn off wifi from y our device. What is the error message that you're getting from the home screen when you try to download Sprint ID?
