We usually take up any opportunity to hop onto a Wi-Fi network, but it’s frustrating if the connection is spotty or overcrowded. Apple Insider has discovered a new feature in the latest iOS 6 beta that could save you grief in those situations.
Buried deep in the settings menu (Settings > General > Cellular) is a new option called “Wi-Fi Plus Cellular” that is turned on by default. It will probably be useful when connected to a public Wi-Fi hotspot that’s under major stress — your iPhone will automatically switch back to your 3G or 4G connection. While it’s not a major change, it’s bound to be a much-needed addition for those who are more worried about being connected than going over their data allowances. [Apple Insidervia The Verge]
