Hi guys, I recently switched from an iPhone 4S to a white iPhone 5 and while I'm perfectly fine with all the settings (I owned all the iPhone release since iPhone 3), I'm having some trouble with the Settings -> General -> cellular switches. In my former iPhone (4s) I had a switch to turn on/off 3G that I used to save battery life while maintaining data (EDGE is more than enough for mail, meteo update and so on ). In the new iPhone 5 the only switch I have is Enable LTE on/off, and disabling this option keep the phone in 3G mode. But reading this forum and others, I saw posts of other people speaking about turning 3G on and off with iPhone 5, so I'm puzzled. Is this related to my operator's sim (4g enabled) ? Thank you in advance for the help.
