I am working on an iPhone app for a client.
At the moment they have a main page for viewing a list of events and then a "filter" button to press to take you to another page to set the distancea away from the users current locations. The filters just affect that page.

And that got me to thinking whether there is any best practice for using popovers in an iPhone app?
Oh yes and are they called popovers or popups? (:
Here is an example of a popover:
