    I have just installed iOS4 on my 3GS but I can't see how I can use the new multitasking function.

    Make sure the app is capable of multitasking, then check your dock.

    it's sad to think that anyone who has never used it before, until now, will think this is true multitasking

    should be called recently used

    Updated apps have some semblance of multitasking. GPS apps will continue to run in the background, streaming music will continue to run. Others well "save states" so they can quickly load back up to where they were.

    It is just somewhat limited multi-tasking.

    Actually that is not sad, it's excellent, because they will notice that their apps load instantly, and they can easily switch between their apps, and yet they have no drain on battery or performance. That's an excellent future for multitasking. Not sad at all.

    Oh FFS, get over it. Apps that have a legit reason to multitask, do. Those that don't, don't chew up resources. Apple is correct that this should mean absolutely NOTHING to the user. If you really want to micromanage your phone, buy a Droid.

    I am coming from a palm pre which with it's cards has the easiest and most effective for of multitasking onthe market IMO, but now that I have the iPhone 4 I am still glad I madethe switch. The multitasking works good and the apps that have been updated work awesome. I don't understand how everyone has to complain how the multitasking sucks so badly. Want better multitasking get another phone. Constructive criticism is one thing, but what most people do on here is just complain and complain.

    here is something to look at.

    Take a jailbroken iPad, install Backgrounder and (i forget the name) an app/mod that displays memory usage in the status bar. Launch an app then set it to run in the background.

    When you go back to the springboard, the app is still using all of the memory it was using when it was launched. What task is the app doing that you need it to continue to use up all of that memory in the background, and thus battery power.

    In order for the app to stay running in total, the active memory needs to be kept active via the battery.

    Apple's method is to make the app slim down it's footprint when it is not the foreground application. Currently with the iOS Multitasking API, this is via...
    Music Playback (Pandora, Tuner Internet Radio, etc)
    GPS (Navigon)
    Local Notifications (aNote)
    VoIP (Skype)
    Fast App Switching via Saved States
    Task Completion for file uploads

    The above instantly give apps more power than they have ever had before on the iPhone, and make them far more stable than the Jailbroken methods.

    When it comes to websites, content is king. When it comes to cell phones and mobile devices, battery life is king. It's easy for a desktop to support full multitasking, it's plugged into a constant power source. Its easy for a laptop to support full multitasking, it's battery can sometimes be 2 or 3 times larger than the iPhone itself.


    What we need to be discussing is what do we want to see Apple add to the Multitasking APIs in future releases of iOS? Here is my one suggestion...

    Background Fetch API: Make the "Fetch" function of Mail global so any app that you want to have Fetch data (Twitter timeline), is able to at set intervals.

    @jello
    you always has a way of convincing people to think outside of the box, you should be in sales. haha

    @Duvi
    good point. i guess in this day & age multitasking is subjective and Apple is creating their own version of it


    Jeff, love the FFS comment... and i'll never go to a droid. thank you

    I am really happy with the multi tasking. I have to admit that I'm really wanting the skype update, but that's not Apple's fault. I was recently at the hospital w/ my mom and didn't get cell signal but had guest wifi. I was able to stay in touch with family through text+ online working in background so it was a nice step in for texting updates.

    To be iPhone 4 compliant and approved the apps should have to be Retina Display ready and multi-task, sleep, recently used etc. Otherwise they can be misleading with the iOS4 tested or approved info.

    I remember when i 1st got this i4 and played with the multitasking, i didnt like it too much because i was still used to Proswitcher and Backgrounder but if u ask me now... i love the way Apple put the multitasking option on here, im used to it and i actually love the fact that most of the apps saves its state to where u left off thus managing ALOT better battery life then my 3G|s|.

    to be honest I dont even use the multitasking feature because it just fills up with to many apps every once in a while I go in and delete them

    IF you are jailbroken you can turn off multitask by editing the N82AP.plist in the SpringBoard.app

    Noaim, there is absolutely no reason to remove the apps i the switching area. None. If you don't use it, just forget they're there.

    No need to delete items from the multitasking
    bar. It's not needed unless it's location based,
    VoIP or streaming. Even then, there is usually
    a way to exit backgrounding apps.

    but if u have an app acting up then its a good idea to delete it from the bar, this way u can reload the app fresh

    that has been the only times where I have found myself removing Apps from the App Switcher Tray, otherwise i let the list build. I wonder how many trays long it can be...

    My 3GS starting freezing/acting up a few days ago. Having redone all my folders a few days prior to that, I had the bottom tray full.

    I took every single one of them out of the tray, and the phone was fine again.
    What struck me as strange about this, is that very few of my apps have any b/g multitasking...they were just sitting in the 'recent' tray doing nothing.
    They shouldn't have been an issue.

    Are all the apps you have down in the task bar actually iOS4 tested and compatible. What I found was when I had a few of those running that were not compatible it not only took my battery life down, but used up system resources. However, when I have apps that are iOS4 compatible I don't find it necessary to shut them down.

    For myself as a general rule. I have this habit and it is totally unnecessary but I do it because that is just me. When I charge my phone at night, I close out all the apps and restart my phone. This way I know when I hit the ground running the next morning my phone is good to go with all its resources for the day. Again not really necessary, but it just something I do. I have extremely great battery life and my phone runs perfectly all throughout the day. In fact where as my 3GS use to be at around 30% battery left at the end of the day. I am finding my iPhone 4 is at around 50% or more. So, I am loving that.

    My son has my 3GS and he does what I do each night just cause I told him I thought it was a good idea. He is very pleased with his battery life and performance too.

    They more than likely were the issue, especially
    if they were updated for iOS4. I'm not referring
    to multitasking, but being updated for iOS4.
