  • Apple to Limit iPhone 4.0 Multitasking?


    Apple will be previewing iPhone OS 4.0 to reporters and industry analysts in a special presentation tomorrow that Apple called "a sneak peek into the future of iPhone OS software." Most observers are fairly confident that the update will bring multitasking to the iPhone and iPad, a feature that many users have been waiting a long time for. However, given the hardware limitations of the iPhone - especially older models - some pundits are guessing that Apple will restrict multitasking to certain applications only.

    According to industry professionals and alleged leaks from inside Apple, multitasking in unavailable for most apps because of the load it would put of the iPhone and because of security concerns. remember that the iPhone OS is built on the same Mach microkernel that lies at the heart of the desktop Mac OS X, so it already supports fully-preemptive multitasking. Apple limits multitasking capabilities to its own apps like the phone, Messages, Mail, iPod, Voice Memos or ones that it directly controls such as Nike+. The limitation is always explained by the need to manage scarce resources and prevent the installation malware on the iPhone.

    Thus, Apple is unlikely to allow full-bore multitasking in iPhone 4.0. Aaron Vronko, the CEO of iPhone service shop Rapid Repair, told Computerworld that he thinks that Apple will decide which apps will be permitted to run in the background, a scheme he calls "intelligent multitasking." Giving Apple control over the apps that will be able to multitask makes sense, according to Vronko, "because it lets Apple control the user experience and performance," he said, in a reference to power and memory management. The iPad, like the iPhone 3GS and third generation iPod touch, is limited by its 256MB of RAM, and older iPhone OS devices have only 128MB.

    Though most observers, including analysts like Ezra Gottheil with Technology Business Research (who also gave his opinion to Computerworld), believe that the upcoming fourth-generation iPhone will have some version of the new A4 processor, both he and Vronko claim that multitasking will still overload the device, and that Apple will hobble the system to keep users from swamping the CPU and RAM. In a world where devices like a Blackberry Bold or a Palm Pre can multitask with less available resources, the case is far from strong... but it sounds like one that Apple will make anyway.

      Wait, I thought they were just going to show a beta or something. Why would they release 4.0 for iPhones when iPad is 3.2?

      Multitasking only really makes sense for the iPhone, with the ipod Touch there really isn't a reason to use it.

      Quick reply FTW! That's the one thing that I would want multitasking for is sending SMS and not having to exit the current app I'm in. But alas... a jail broken phone resolves that little issue quite well!

      there not releasing i think there just releasing the details and when it might be available and were not jailbreaking until 4.0 comes out. because of the ipad. if we jailbreak the ipad they have enough time to patch 4.0

      Apple is just fu*king us over....AGAIN!....Watch, i bet it's going to suck so bad that people will be crying to restore back to 3.1.3 or 3.1.2. I'm seriously tired of CRApple limiting the potential of their devices, and SO WHAT about battery life? That's why they invented WALL CHARGERS, PEOPLE! This is what im going to do: trade my 32GB iPod Touch 2G in for an iPod Touch 3G 64GB, wait for untethered jailbreak, then completely ignore software updates from then on, until Apple stops being so f*cking stingy with their devices.

      Because of this, (i was going to order a 3G[s], but now i think i'll get a f*cking MyTouch.

      Things like this actually remind me why I like Windows Mobile. Yesterday, I was on my HD2 riding the train home, Playing Final Fantasy IX, while listening to slacker radio, with an IM service running as well. There arent many times I'll do this, but damn am I glad I dont have to jailbreak to do it.

      In hindsight, while jailbreak is generally a quick operation, the simple notion of not having to do it in the first place is pure gold. Not saying I didnt love my time with the 3GS, but stuff like this reminds me why I left.

      It's not 1995 anymore buddy.

      And apple should do away with the whole OMG HUEG pop-up in the middle of the screen and instead give us a flashing icon in the upper left corner that reflects the type of notification and when you click on it will display more information

      They could do so much better than what they have done with the status bar. Its totally useless right now, unless you jailbreak. I would love to see them adopt the way google handles their status bar (magnification upon touch). Great artists steal, right?

      Ok. Forgive me but...


      ....do the original iPhone and the 3G model have the same amount of ram? I know the 3G is faster but is that because it has a faster processor?


      I tried to find these simple answers online and couldnt 0___o

      1st gen and 2nd gen iPhones have the same processor and ram i believe. The 3rd gen (3GS) has 256mb and faster processor.

      Thats so odd. I always thought the 3G was slightly increased in some aspect. My 3G loads the same apps faster and runs them smoother. Hmmmmmmm

      And apple wonders why people jailbrake their phones... I have multi-tasking on my phone and it has proven to be the greatest feature of the (jailbroken) phone. I doubt app will do it
      right so it doesn't matter what excuse they make for limiting multi-tasking. The fact is it works will on jailbroken phones and other phones so they can do it if they want.

      ok so you dont use it which means that no one else does?? right....

      i keep about 3 things running all the time on my android phone

      examples of what i have running right now

      facebook
      sports scores updates
      twitter
      weather bug
      Google latitude

      it is extremely useful especially on road trips where i can have google navigation running and trapster at the same time

      What the f****

      listen I am an busy person, always on the run, still I don't see any use of multitasking, this is the cry started by some stupid. Compitition, who just wanna be a cry baby.
      ASK yourself how many window user actually work with 3-4 software at a time on their junky window os.
      I tried in my window laptop and what I could see a hang OS which I have to hard restart.
      I use powerful 16 GB power Mac and my new i7 with 8 GB ram, still I don't see any use of stupid multitasking.
      And I can very well understand the reason why apple is going to restrict MT, because it slow your proccessor and kill the battery.
      Now imagine apple give go ahead for all the apps MT enabled, your battery will die in few hours.
      And all the blogs will be full with complaints nothing else.
      see above and i have no problems with my battery getting murdered like you so claim
