I want to update my app to make use of the multitasking functionality and local notifications available in OS4. My question is, if I update my app and make it only available for OS4 and above does this mean that if someone is running OS3 on their phone they won’t get the update? or they will get a warning that they need to update their OS? What I don’t want to happen is for them to update their app to find it no longer works? If the final situation is what will happen, how do I write the code to find out what OS is being used?

Thanks

    If you update your app to be 4.0 only, and also mark your app as 4.0-only in the Store, then people will not even see your update.
