iPhone Data Usage Monitoring
<p>I'm trying to build a "Data Usage Monitoring" iphone  app as a quick demo, but haven't been able to figure out how to get CellularData/Wifi usage statistics programmatically.</p>

<p>I know this is possible, as there are several apps in the app store for this (DataUsage, DataMan). </p>

<p>I know for a fact that these are not scrapping the cellular provider's pages to get the data usage, so I'm wondering how they are able to achieve this. </p>

<p>Couldn't find anything in the iOS 4.2 SDK Documentation.</p>

<p>I'm guessing they are somehow getting the data that is displayed under "Settings -> General -> Usage", </p>
