MacRumors is reporting that it has been seeing increased traffic from devices on Apple networks running iOS 7.0.4. What does this mean? Well, not much for now, but it could indicate that Apple is prepping the next release of iOS 7 – 7.0.4 in this case. iOS 7.0.3 was released to the masses on October 22nd, and as MacRumors points out, that is also the first day that it saw traffic from devices that are supposedly running iOS 7.0.4. Being such a small point update, it would most likely just be a bug fix or feature enhancement. Nothing too major will come until iOS 7.1 most likely.
Speaking of iOS 7.1, MacRumors has also been seeing traffic from Apple servers on devices running that as well. Those have been popping up in small amounts since much further back, and have seen increased numbers throughout October. Apple has released developer betas of point updates before, such as iOS 6.1, so there is the possibility that we will see such a beta seed before we see the iOS 7.1 update become publicly available. Obviously, we would expect to see iOS 7.0.4 come before iOS 7.1.
