August,
Just to second what Randy said...
Agreed on the general rule of thumb of using object detection and
avoiding user agent detection for Web sites. However, if you are
developing an application specifically for iPhone/iPod, then user
agent detection is a valid way to go. Plus, since an iPhone app is
written for a particular viewport (and might rely on iPhone service
integration), then searching for "iPhone" (and/or "iPod") is preferred
over "Mobile" and "Safari". After all, they could release a iWidePod
that had completely different viewport dimensions.
