iOS 5.1 Code Basically Confirms 4G LTE iPhone, FaceTime Over 4G in the Works

A few lines of code inside Apple’s latest iOS 5.1 release pretty much confirm that Apple is indeed, as most of us suspect, working on an iPhone capable of running on 4G LTE networks. It appears the device will not support voice-over LTE (VoLTE) at first, however, as one of the strings of code reportedly tells a user that turning on 4G will end an ongoing phone call. “Enabling 4G will end your phone call,” the code, discovered by Cydia developer Krishna Sagar says. “Are you sure you want to enable 4G?”

In addition to the above strings, iOS 5.1 also suggests that Apple is working on supporting FaceTime over 4G LTE networks, a feature that is not currently supported on its brand new 4G iPads. “Disabling 4G will end FaceTime,” the code says. “Are you sure you want to disable 4G?” Here’s the entire string discovered by Sagar:

“4G_ON_CALL_CANCEL” = “Cancel”;
“4G_ON_CALL_OK_DISABLE” = “Disable”;
“4G_ON_CALL_OK_ENABLE” = “Enable”;
“4G_ON_CALL_WARNING_DISABLE” = “Disabling 4G will end your phone call. Are you sure you want to disable 4G?”;
“4G_ON_CALL_WARNING_ENABLE” = “Enabling 4G will end your phone call. Are you sure you want to enable 4G?”;
“4G_ON_FACETIME_4G_WARNING_DISABLE” = “Disabling 4G will end FaceTime. Are you sure you want to disable 4G?”;
“4G_ON_FACETIME_WIFI_WARNING_DISABLE” = “Disabling 4G may end FaceTime. Are you sure you want to disable 4G?”;
“4G_TEXT” = “Using 4G loads data faster, but may decrease battery life.”;
