iPhone 5 rumors: hints at 4G iPhone found in iOS 5.1

An unofficial “confirmation” comes from codes found in the iOS 5.1 discovered by Cydia developer Krishna Sagar (via iDownloadBlog).

The code strings contain the text: “Enabling 4G will end your phone call. Are you sure you want to enable 4G?”

Since the new iPad doesn’t have phone features, many assume that Apple is preparing the ground there for a 4G iPhone.

Reference to FaceTime over 4G is also included in the code strings:

“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.”;

A blogger even posted a video of the codes found in iOS 5.1.
