Today, when the Os 4 for the iPhone family is about to be released, the most spicy discussed thing is its multi-tasking. However, there hasn't been much discussion on the importance of multi-tasking to the commonplace user, yet there are many questions on this topic, like whether it will be found useful for the business willing to safely merge the iPhone family into its network. Besides, will this multi-tasking feature sway the carrier dearly reclaiming the biggest part of the abused bandwidth of the last mile, stacked with 90% junk email?
To start with, the iPhone already features multi-task, so it's not such a new feature in fact. It's already able to listen for incoming texts and phone calls, while letting music to be played with awaiting updates. The current version of the iPhone Os uses preemptively multitasking Mach/Bsd kernel, exactly the same as Apple's desktop Mac Os X. Meanwhile, consumers see multi-tasking as the potential to run more than one third-party program simultaneously like on desktops and laptops.

Actually, broad multi-tasking is an needful even from the conventional security point of view, let alone the users' convenience. That is not the talk about the security of the external look of the device - that's what iPhone 4 case can do for you. That's about the software security. Think of it: each time you generate a Word document or something, there's a large estimate of security processes in the background, spicy the needful power, and, of course, sharing the Cpu resources and memory. At the very least, anti-virus software, along with anti-spam, should run constantly, at the same time as the Vpn and personal firewall help to get the device completely.
The private consumers and clubs commonly run various versions of security software of different brands to keep the highest rate of hostile code and activities detection. At the same time the user is busy with typing, listening, or downloading rich content. So, it comes needful for tens of millions users of Apple's iPhone to have multi-tasking in the Os 4, because it seems to be needful just from a security point. However, it's just a false feeling and verily doesn't matter. Apple could do the same as Android and Windows movable that allow any type of application to run whenever the user wants it to, facing the same pack of conflict problems and law doing that were discovered on the commonplace Pcs. As soon as Apple's A4 processor has up to 4 cores, Os 4 would be able to isolate the internal law processes from the others on one core while using the others to administrate third party software.
One more potential look on Os 4 may consider multi-tasking allowing one third-party application, for example, native Safari and mail running simultaneously, while permitting two, three, or whatever estimate of Apple ownership applications running, managed by a kind of Command-Shift to switch between them. In fact, the definition of multi-tasking is not "running as many applications as the user wants." On the contrary, creating rational restrictions to keep user's palpate inescapable is one inescapable coming for the movable Os developers.
So what would happen to security in this case? Actually, smart phones are only small computers, and are therefore field to the same weaknesses as of the commonplace Pc, letting alone jail broken iPhones. By the way, the smaller devices win in the fabricate and look, because you won't able to put a colorful iPhone 4 cover on your Mac to raise your mood. But if we go back to the software problems and fantasize that Apple would agree to let an unrestricted estimate of security applications to run simultaneously (multi-task), then it would imitate the state of security where the user is the responsible one for managing them all. Besides, each security application would be loaded onto and run from the endpoint. However, one should agree that although the private consumers need security and clubs need it for compliance, such unrestricted coming to security (even in Os 4 environment) faces several questions:
1. How long will the battery live, even that of the iPad, with numerous security applications being loaded and run constantly?
2. How big is the share of processing power and storage that will be required to ensure the highest level of security?
3. Inspecting preemptive multi-task, which of the processes will take priority over the others, especially if they are able to sway both security and performance?
4. Assuming that the security should be running at all the times, will the users have to open all the security services every singular time they turn their device on? If compared with Os X, the consumers there are able to agree applications launched automatically at the start in "login items", and this feature verily demands a broad recipe of multi-tasking.
5. What skills and knowledge will the buyer need to get to be able to find, install, configure and operate countless security applications?
6. While using time-based security balance, how will the use of a smart phone endpoint, as compared to the cloud, sway the last mile doing in terms of handling richer content and security?
7. What should user do when turning his phone off for the night to turn it back on in the morning? Assume that the buyer is only intended to check the email, but will have to wait while the multi-tasking iPhone finishes performing a series of security actions first.
8. Remembering that the resources of iPhone are more dinky than those of an commonplace Pc, how often do security signatures, profiles, and alerts need to be updated?
Since Apple's coming depends on ready intelligence, it seems that it is going to serve the user palpate like that in Expose, which allows them to switch easier between the running applications. However, it's not quite clear if it means that the buyer will be able to watch video on YouTube and then swiftly enough to switch over to email, favoring it by essentially pausing YouTube. You could argue it's multi-tasking that kernel manages. But, nevertheless, this coming still won't allow to implement the customary ways of securing the device. And it doesn't matter which of the multi-tasking coming will be chosen to be introduced into iPhone Os 4 or beyond, if it fails to tackle the security problems with conventional methods. No matter if it is iPhone running Os 3 or 4, or even X, or the multi-tasking Symbian or Android, since it's clear enough that consumers shouldn't rely on the phone seller for security, just as nobody thinks it to be the Pc vendor's concern for the whole duration of digital century. In fact, securing all current and hereafter versions of foreseeable movable technology will only mean a creation of a verily integrated get smart phone framework and architecture that is able to work in the cloud.
So, if we look from a security point, it doesn't verily matter what way Apple will choose to fabricate multi-tasking for the Os 4. Since the user palpate is a priority, we can guess that most of the consumers don't dream about putting the security at the top of the list of what they want to do in the morning. Just fantasize what can happen in merge years when over 2 billion movable users chose to get their device only with iPhone 4 case, but not with useful applications? Shall we find it out?
