What is the iPhone equivalent to the \Windows\System32\Drivers\etc\hosts file?
<p>I'm working on a web application and need to debug a problem occurring only on the iPhone.</p>

<p>I can reach the site on my dev box by typing its ip address into Safari (on my phone), but the domain is significant to the application, so I'm going to have to update my config in multiple places every time my IP changes.</p>

<p>What would be ideal is if I could configure the iPhone to always point to a specific IP when I enter a specific domain, just like the C:\Windows\System32\Drivers\etc\hosts file.</p>

<p>Is there a way to do that without jail breaking my phone?</p>
