For some reason, my iPad redirects to mobile version of websites. For example in Facebook, it redirects to the mobile version. I have to click on the full-site in order to view the webpage normally. Same goes for the Yahoo webmail, when after logging in, it tells me that the Safari browser is not supported, and I can continue by switching to the classic version.

This only happened last week, previously both wesites behaved normally. Anybody else experience this?
