Do you hate when your iPhone doesn't automatically switch to 3G if your Wi-Fi connection is too slow? A new feature in iOS 6 will solve this problem. The new option called "Wi-Fi Plus Cellular" allows your iPhone to automatically switch to a cellular connection when Wi-Fi isn't doing the job. iPhone owners can also manage their data usage by toggling specific services on and off. As you can see from the picture below, the cellular option allows you to turn off access to iCloud Documents, iTunes, FaceTime, Passbook Updates and Reading List.
The "Wi-Fi Plus Cellular" option was discovered within the Settings menu in the latest iOS 6 beta by AppAdvice. The blog also discovered a toggle for Shared Calendar Alerts within the beta. When enabled, the new feature will notify you whenever the shared calendar is modified.
