Looking for virtual mobile browser for desktop

Hi

I am looking for a virtual mobile web page to show (on a desktop browser) what standard and mobile configured web pages look like on a mobile browser.

Initially I am looking for some live pages that will do this, then I want one for my own site.

The following is the closest (i can find) to what I am looking for.

Devshed blocked the URL GREAT !!!
- search for redrome
The browser in this works (I only want the browser)
Open source code for this is available on the site

Devshed blocked the URL
- search for iphone4simulator
Can't remember how this works (slider does not work on iPad i am using)

Devshed blocked the URL
- search for gofoood
This site just shows its own mobile site (rubbish content, but looks nice)

I am sure you will find sites - if necessary send me a PM

If anyone can point me to other sites that will do this - please do.
If anyone would like to quote me for a page with only the mobile safari browser- please do.

Note googles new Howtogomo has too many buttons to press and is sort of broken at the minute, it is supposed to simulate 3G loading times, but most sites never actually load

Thanks Colink
