If you have an iPhone, hopping on a wi-fi network is good if you want to connect to an AirPlay device, or wi-fi based storage device, or save some battery. But if the internet connection is really crappy or non-existent, that means you're essentially cut off from the world (unless you're trying to talk). But a new feature discovered by Apple Insider in the latest iOS 6 beta fixes that.
Buried deep in the settings menu (Settings > General > Cellular) is a new option called "Wi-Fi Plus Cellular" that's turned on by default. It will probably be useful when connected to a public hotspot that's under major stress. And while not a major thing, it's a much-needed addition that increases the functionality of the phone.
