Force wider viewport size in iOS Safari?

Is there any way in iOS Safari (or third party app) to force a larger viewport? I'm fine scrolling around a website to see content but I'm not fine with sites hiding content when I use a narrower than desktop device.

Ideally I would like to set my width (say 1024) and then have my iPhone browse with that width and drag around to see the page. Kind of like magnifier but in reverse.

You can use the aptly named iOS app, Desktop Browser to do this. Here's what a site looks like in Safari on an iPhone:

Here's what the same site looks like in the aforementioned app on the same iPhone:

I'll bet there are other apps out there that do this. Albeit a little rough around the edges and ad-supported, this one is free and gets the job done.
