For those of you who have gotten their mits on the newly released Apple iPhone 4S, you may have noticed an option missing out of the Network Settings. Most people don't require the setting, or even probably know its there, but its there and its useful to some.
In Network Settings, "Enable 3G" is missing, which gives you the ability to manually shut off 3G data. It can be disabled for multiple purposes, such as saving as much battery life as possible, or when you're at home and don't require 3G data as your own your own Wi-Fi network.
It can even extend to the point of where you might only want it on when you're away from Wi-Fi networks and these days, there's Wi-Fi networks everywhere. Personally, I'm connected to Wi-Fi at home, then at work or even at friends house or when I'm visiting family. The only time I require 3G data is when I'm out and about or on holiday.
But, its definitely weird for it to not be included...
