I just bought the DS 1200. I am using it with the iphone3. I love the compact size and want to use it as my alarm clock. However, after setting the alarm and docking with the soundring, the app does not stay running after a while. The iphone goes back to my normal background. As a result, the alarm does not go off. I have the autolock override turned on, but this does not solve the problem. If I can't solve the problem, I'll have to return the product.
