Apple: iOS 5.X should handle "Over The Air" updates

Post by sniper3d »

Automatically translated from French.

One of the main criticisms of iOS is its operation in updates. From the original 1.0 version to the current 4.3.3, no patch has ever been applied incrementally. This means that with each version, you absolutely must download all of iOS, which is hundreds of megabytes. The situation could change with the 5.X branch of the system.

Updates that are far too bulky

We saw this recently with the 4.3.3 update for iOS that came to reduce the geographical tracking problem: even if the update was not of great scope, you had to download the entire operating system. Depending on the device, this could represent more than 650 MB. This weight presents multiple problems. Thus, not only does this require appropriate connections, but users may also be demotivated by an operation deemed heavy.

Such weight for the slightest modification will also not go in the direction of bandwidth consumption savings. And it is precisely this lack of savings that currently makes it impossible to put OTA-type updates. This term, for Over The Air, means that you can receive an update or patch directly on your phone wirelessly. This can be done via WiFi, but also and especially via 3G.

OTA mode unfortunately requires limited weight for updates to be perfectly viable on a platform. Indeed, excessive weight would make downloading too long and could too easily reach the monthly threshold in the data plan. Apple must therefore revise the architecture of its system to be able to issue small updates when they are sufficient.

Revised architecture for iOS 5?

And indeed, according to 9to5mac, such a project is indeed in preparation at Apple. Work on iOS 5, which is expected to be unveiled at the WWDC conference in June, should focus in particular on system architecture. From a certain 5.X evolution, iOS would be capable of receiving OTA updates, which necessarily means incremental operation.

However, OTA updates necessarily require the agreement of mobile operators, in the case of retrieval via 3G. This means that in Apple's case, it will have to negotiate with each operator separately. According to 9to5mac, Apple and Verizon have been in talks for several months on this subject.

If Verizon gives the go-ahead, then the iPhone will be able to receive reduced-size updates directly, without going through iTunes. If this feature is indeed part of iOS 5.X, iPod Touch and iPad should also get it, assuming this type of update could be done via WiFi, which would be logical. While talking about WiFi, by the way, there have long been rumors of synchronization of iDevices without USB cable connection, particularly for adding music. One and the other rumors would thus suggest a more autonomous operation of the devices.

Apple should lift the veil next month on iOS 5, but it's not certain that OTA distribution will be specifically addressed... if it is indeed planned.
