By now it should be pretty obvious to Apple fans that the iPhone 5 will be getting 4G LTE technology. But just in case it isn’t, here’s yet another reason why it’s apparent that we will see a 4G LTE iPhone 5: the newly released iOS 5.1 has the code already in place for a 4G LTE iPhone 5.
Jailbreaking is something that many iPhone users are proibably familiar with–though it’s not normally something that can unlock secrets about an upcoming Apple phone. However, in this case the code that is accessible through jailbreaking is helping us to see that Apple has already accounted for an iPhone 5 with 4G LTE.
The source–an anonymous tipster to the iDownloadBlog–used the jailbreak-exclusive app iFile to find the Network.strings source code for iOS 5.1. This source code is responsible for controlling the network functionality of the iPhone 3GS, iPhone 4, iPhone 4S and the iPhone 5. And according to the screenshots that the tipster took and forwarded on to iDownloadBlog, there are numerous mentions to 4G LTE in the code.
Now you might be saying, well, couldn’t those mentions just be about the 4G LTE iPad which also runs on iOS 5.1? That’s a fair question, as Apple would obviously have to write in code for the 4G LTE in the iPad. However, the proof is in the details. When looking at Network.strings, we can see several lines of code, including:
“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 call.”;
You don’t have to be a coding expert to tell that these lines of code are referencing a phone (such as the iPhone 5) and not an iPad. The iPad does not allow users to make phone calls; only the iPhone does. And the references to 4G also make it painfully obvious that these codes aren’t relevant to the current iPhones, as none of them support true 4G LTE. Therefore, these lines of code only point to one thing: an iPhone 5 with 4G LTE.
The code also shows that iPhone 5 users will be given the choice to either use 4G LTE on their iPhone 5 or use the slower (but perhaps more battery efficient) 3G. Not only that, but it appears that FaceTime on the iPhone 5 will also support the use of 4G LTE–which means iPhone 5 users won’t be bound to using Wi-Fi to make FaceTime calls. This is extremely interesting and very much unexpected as FaceTime calls can eat up a lot of data, which is why Apple made it so that they required Wi-Fi in the first place. With FaceTime working on 4G LTE, this makes it a lot more convenient for iPhone 5 users to video chat with their friends on the go.
As always, this is just a rumor; however, given the fact that iDownloadBlog and others were able to duplicate the findings, a 4G LTE iPhone 5 does seem even more likely now.
