Determining iPhone Model
<p>How do I determine which specific model of iPhone I have?</p>

<p>I know about [UIDevice currentDevice].model will tell me if it's an iPhone or an iPod Touch.  Will this tell me if I have a 2G, a 3G, or a 3GS?</p>

<p>Thanks.</p>

<p>EDIT</p>

<p>This also becomes important to me when identifying between a first gen iPod Touch, and a second gen.</p>
