Best mobile simulator for website

I came across few iPhone simulator which are merely an iframe running in smaller resolution to check the mobile compatibility of the site.

This method is not capable of checking the website which detects user agent and paves the website according to the device.

Another, method is to change the user agent of the browser and trick the website to show up as it should look on the mobile phone or any other device.

For example, my default user agent is set to :

Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.2 (KHTML, like Gecko) Chrome/22.0.1215.0 Safari/537.2 AlexaToolbar/alxg-3.1

Well, the above string shows that I'm using windows NT device and installed Mozilla, Safari(AppleWebkit) and Chrome - including other stuff.
