IE9 in Windows Phone 7 can be rather ambiguous, and doesn’t always register as a mobile browser with a lot of websites, that morph when confronted with an Android or iOS device, into a more useable mobile page. While User Agent Switcher can fool a site that your Windows Phone is another device, it can not add flash, it is still the native browser in a shell.
It will though simulate a range of browsers, in an attempt to elicit a different rendering of certain sites, from iPhone, iPad, Android smartphone and different desktop browsers.
It’s rather novel, although not completely convincing in the way it renders some pages, but as you can see above, Gmail looks a lot like it does in a browser on Android, and the Australian forum whirlpool defaults to it’s mobile page when using the iPhone agent. Basically if you know a site that reacts a different way when using one of the alternative agents, and like the way it performs on your phone, User Agent Switcher will give you that experience.
You can’t import your favourites from IE, and there is no access to browsing history, you will have to input the URL of each page you want to navigate to using the app, although it will let you save favourites as you go. It’s also one of the few apps that I’ve seen for Windows Phone that has a dedicated exit button, not leaving in running in the background.
The developer also seems to have a sense of humour, adding a few odd touches. If you think User Agent Switcher will be useful to you, why not give it a try, it’s free in the marketplace.
