Custom header description in UITableView
<p>Is Apple using a documented method of the SDK in Settings.app, or is it some kind of custom cell / custom header description of a grouped TableView ?</p>

<p>"Storage" is <code>titleForHeaderInSection:</code>. What is "8.6 GB Available - 5.1 GB Used" ?</p>
