iOS 5.1 system files suggest LTE iPhone

Posted by: Brett

iDownloadBlog has taken a peek at the file system on a jailbroken iPhone running iOS 5.1, which was released two weeks ago. What they found was evidence that suggests an LTE iPhone is in the works.

iDownloadBlog found three different files deep in the file system of iOS 5.1, all three which suggest an LTE iPhone is in the works, as well as FaceTime over 4G being considered by Apple. The first two files were for the new iPad’s settings for LTE data (but can, theoretically, be applied to the next iPhone). The last file was the most intriguing as it showed strings for 4G over phone calls (ruling out that it is for the iPad) and 4G FaceTime strings, suggesting Apple has considered and is now testing FaceTime over 4G. FaceTime is currently only supported over WiFi, even if you have a cellular connection.

“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.”;

Cult of Mac has contributed their two cents to this finding by saying the strings could just be for the HSPA+ connection the AT&T iPhone 4S uses as the device shows 4G instead of 3G in the top left corner on the status bar once updated to iOS 5.1, the iOS version in which these strings were found. They note that Apple distinguishes 4G by the HSPA+ technology (a faster version of 3G, but not LTE) and real 4G by “LTE”. Having said they, they think the system strings above would say “LTE” rather than “4G”.
