This is really incorrect on a number of levels. If you have a categorical misunderstanding about something that's one thing, but don't perpetuate it when you advise people. It's on the borderline of dishonesty whether you're actively making stuff up or not.
For example, there is no actual multitasking in iOS 4. It's a hacky method that in some respects fakes the functionality of multitasking, but for 99% of the time it's not going to expose any new functionality that wasn't already there in the first place-- IE, a letdown.
By jailbreaking, you can install Backgrounder, which allows the same sort of application multitasking you're accustomed to on a Mac or PC.
If the limited "fast app switching" in iOS 4 is sufficient for you then that's excellent, but just because you personally found no use for jailbreaking doesn't mean there is no use for jailbreaking, nor does it mean you should scare off people asking questions by hyperbole and misinformation.
Here's a newsflash, installing anything on your computer can use up RAM and cause crashes and introduce security vulnerabilities. The same lessons apply in the iDevice world as they do traditional computing. Common sense is all you need, I personally don't need to rely on Apple or Steve Jobs holding my hand for me as I use devices I paid significant money for.
Feel free to disagree with Apple’s use of the term “multitasking” but don’t call me dishonest for agreeing with it
🙂 In my view, Apple’s multitasking is a more modern, far superior version of multitasking. Not 1980s-styl brute-force multitasking that burns RAM and battery. And yes, brute-force multitasking also allows certain things to be done.
Which is why my question was a key one to ask: what, exactly, does iOS 4 NOT do for you that JB will? What app, specifically, do you want to multitask in a different way?
Most people have no answer for that. If the OP does, then like you, he may wish to JB. If not, then it’s to be avoided: it offers risk without benefit in that (very common) case.
My advice was very sound and accurate, and if you think I have some info wrong, let me know exactly what. I never said JB WILL cause problems, only that it MAY. This is fact.
And your advice to use “common sense” and manage your RAM like you would on a desktop computer is a good example of why most people shouldn’t JB. iPhone/iPad are built to be easier to use than a desktop. You shouldn’t have to manage RAM manually, and the more you must do so, the less convenience. So why do it? If you have a need for it, that’s great. I’m suggesting not everyone has a need for it, and that non-techy users especially should hesitate, because they’ll have some extra work and complexity and troubleshooting ahead of them. If you feel EVERYONE has a need for JB, then that borders on dishonesty
🙂 (No, I don’t think you believe that—it just sounds that way.)
JB is not a religion, and I’m not telling people to stay away from it. I’m countering the impression that it’s for everyone. It’s not—it’s unnecessary for most people, and they need to have info to make that decision. Whichever way they decide is great—I plan to have one JB and one non-JB device myself.
A good example to help the OP would be: what apps, specifically, do YOU need JB for? Are they apps that have no iOS 4 alternative? Why are they better than what’s on the App Store? With specific examples, the OP can judge how important it is to him.
