iphone programming adivce
<p>Hello I was wondering if there are any methods that would allow me to interact with the iphone users. What I mean is like  UIALERTVIEW of some sorts that will popup and update them with a status. But I don't want to have a fixed status, but one I can change anytime I want, like say if there is a day off, I want to provide a status over the air and when the user opens the app it will show the new message.</p>

<p>Is this even possible?
If there are any other alternatives please list them</p>
