If you want to look how a test (or any other site) will behave in an iPhone safari from the comfort of your Desktop, do the following steps:

Windows 7

  1. In Windows Explorer, go to
    C:\Users\YOUR_USERNAME\AppData\Local\Google\Chrome\Application\
  2. Create a link to chrome.exe (right click, Create Shortcut)
  3. Alter the target property in this shortcut:

From: C:\Users\YOUR_USERNAME\AppData\Local\Google\Chrome\Application\chrome.exe

To: C:\Users\YOUR_USERNAME\AppData\Local\Google\Chrome\Application\chrome.exe --user-agent="Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419.3"

I use the Web Developer extension, so I can resize my window to iPhone’s defaults (320×480 or 480×320)
