Can you force a mobile site on your iPhone to show full desktop view? Is there a way to force websites, when browsing them on your phone, to go into full desktop view? For instance, when I go to the NASCAR website on my phone, it displays a mobile version. But the mobile version doesn't give everything the full desktop site does.

I can trick the site to think I am browsing it on a computer by putting something after the .com,like .com/News and it will work, but then when I go to their homepage by clicking on the logo, it redirects to the mobile version. I am using an Apple iPhone 4 for my device.
I don't think you can do this in Safari on the iPhone but you could use a 3rd party browser app. Many of those will let you set the browser agent. One browser I know does this is  'Atomic Web Browser'. This may not work in all cases as some websites may use other ways of determining which content to show, for example, some will detect the screen dimensions.

I've tried this on my iPhone with Atomic Web Browser. Within the browser, I went to settings, 'Identify browser as' and selected 'Safari Desktop'. Then I went to nascar.com and tapped on the nascar logo. It showed me the desktop version of the page.

I checked in mobile safari and doing the same indeed took me to a mobile version.
