Mutitasking in iPhone Os, this is how it could be

The jumble of hypotheses open: the rumors mill works at full speed now that Cupertino's announcements are just a few hours away: the surprise event organized in Apple's internal theater that could pave the way for the new generation of Apple's operating system.

The rumors that circulate more insistently are related to the type of devices on which iPhone OS 4 girer and its characteristics. From the first point of view, some argue that Apple will take the opportunity not only to talk about the features of the new release of its operating system, but also which hardware will support it. And here the surprise, according to some rumors, would be double: iPhone OS 4 will turn not only on iPad but also on the iPhone not yet announced and arriving for the summer.

However, the announcement would be that of an expected multitasking version for the iPhone and iPad. Not a "total" multitasking, like that of Mac and PC, and not an "embryonic" or "incomplete" multitasking like the current one (some applications, such as Mail and the iPod functions, run in multitasking right now). Instead, it would be an "intelligent" multitasking, in which in essence it would be Apple to decide which type of applications can run in the background or how to be suspended.

For example, explain rumor sites on the basis of logical speculations as well as advances, Apple would have worked on a priority system according to the type of app, with verification by the technicians themselves. app by app. This is possible given the "closed" nature of the iPhone and iPad environment. In essence, apps would run in the background only if necessary, otherwise they could simply be "frozen" when moving to another process, or closed without appeal.

Three examples to explain the concept: an app that remains open even when it passes in the background could be a chat program such as iChat or Skype. In this case, instead of simple notifications, a service would be launched that would allow the individual developer to obtain results similar to those of a personal computer. This would be "total multitasking" limited to some applications.

Other apps would have access to "virtual multitasking" and would actually be "frozen" when the user decides to switch to another app. This saves the memory status (which windows are open, which documents, which features). The case could concern a word processing, a program for reading digital books, for example.

Finally, there are software that makes no sense keeping open while doing anything else, such as games and videos. In this case, multitasking would not exist at all and, by Apple's choice, the aforementioned applications would be closed exactly as it happens now.

The three cases of multitasking (or non-multitasking) would all be defined as "intelligent multitasking" and controlled by a series of technical procedures and categories chosen by Apple with the criterion of maximum device functionality and battery saving within the limits of the possible with regards to its appliances.

Still, according to other rumors, to keep these news company there are those related to Quattro, the company bought by Apple a while ago and specialized in interstitial advertising and mobility. Apple would have worked on the insertion of the technologies necessary for the operation of this technology directly within the operating system. The aim is to allow developers to make the best use of it, as an alternative to what Google does for its platform on the web.

Finally, the processors. The great success of critics and apparently also of public for Apple A4, the first CPU for a long time made with the fundamental contribution of Apple itself, would be the spring to load and start a more ambitious plan: to have a totally compatible version and partially reduced also on iPhone and iPod touch. This would be a significant leap, because A4 and its variants would allow the creation of technologies and software that would otherwise be impossible for the iPhone / iPad couple (not to mention the iPod touch). This would arrive in a few months, at the price of incompatibility, some rumors claim, of the old applications born in the iPhone environment and which should be substantially rewritten.

Macitynet will follow the presentation of iPhone OS 4.0 with a live broadcast in Italian starting from 7pm tonight, relying on the various US sites that will be present at the event. This page to follow the live broadcast with comments before and during the event.
