Will Apple’s iPhone 5 feature 4G? According to some lines of code buried inside iOS 5.1 it will.

This isn’t all that surprising though. Apple is, after all, now a company that does 4G, which means that all of its products from here on in, be they smartphones or tablets, should feature support for the next-generation mobile data standard.

4G or 4G is still something of a futuristic technology in the UK, like hover boards and self-drying clothes, whereas the standard is now readily available in parts of the US. Of course this will change in time – latest reports suggest 4G will be a done deal in the UK by this time next year.

O2 is already testing its own 4G network across London as we speak.

So a 4G-enabled iPhone 5 is definitely a good thing, particularly since it probably won’t launch until the latter part of 2012 anyway, which should – hopefully – coincide with some significant developments in the rollout of 4G in the UK.

Back to the iPhone 5: now we’ve seen hints of 4G in Apple’s iOS code before but this is the first time we’ve had confirmation (of sorts) that it is actually from inside the code for an iPhone.

Cydia developer Krishna Sagar discovered the following in iOS 5.1’s code: ‘Enabling 4G will end your phone call. Are you sure you want to enable 4G?’

There was also reference to FaceTime calling via 4G as well – see below – and while this could in all likelihood be referring to the new iPad, which is a 4G device, we think the reference to ‘phone call’ is pretty telling.

“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.”;
