One such video (in Polish) shows iPhone OS 4 multitasking and folders:

Kim reports, “We’ve discovered references to Camera Flash in the iPhone SDK (again), suggesting that Apple is working on a physical camera flash for future versions of the iPhone. Apple has also integrated Grand Central Dispatch into the iPhone OS — a technology introduced with Snow Leopard to ease the use of multi-core processors.”

  1. Good to hear about camera flash. Yes it’s a bit more drain on the battery, but no matter how good the lens is in the iPhone 3GS, I’ve had so many shots ruined in medium (never mind low) light that I don’t even bother trying anymore.

  2. Hmmm…

    Multitasking… how significant you actually are. Skype notifications. Hmmm….

    I was thinking about this during the iPhone 4.0 discussions yesterday. I’ve been thinking about it a great deal actually.

    About 3 years ago I finally dropped my land line. I had no need of it. I found I seldom used it and it amounted to a little over $800 per year. All my calls were either VOIP or cellular.

    Now I find that I’m at a similar crossroads with cellular. AT&T;charges me $1728 per year for iPhone service. Ironically, most of my voice communications are IP based. My estimates are that cellular calls for me are less than 1% of my total communications. Even with the cheapest of AT&T;SmartPhone services that’s $1200 per year. For nothing.

    Email, text, online text chatting, video chat and VOIP are my primary methods, in that order. Heck, I get more business communication via Facebook than cell calls.

    I have a Skype number. I have a Google Voice number. Google sends me free email transcripts of voice mail. I can forward Skype to Google and get free transcripts of Skype messages. Anyone in the world can call me on Skype or Google.

    I can’t use my phone while driving thanks to the nannies. No use for it there really.

    It would serve me better to get a MiFi device. I’d be my own little hotspot when necessary. My cellular costs would drop from 1728/year to less than 600/year, if I went monthly. If I purchased a block of data, way less than that.

    Even my nifty new iPad (with WiFi only… NO 3G), allows me to send and receive VOIP calls.

    I think today is the day I say goodbye and good riddance to AT&T;.

    All it took was the realization that the iPod Touch would be a primo little VOIP phone thanks to iPhone 4.0 multitasking.

  3. It would be MUCH better if Apple provided developer links to an external camera via bluetooth e.g. the iPad can view a virtual image from either an iPhone or control a BlueTooth-enabled Canon or Nikon still camera or video camera.

  4. Why do so many people have trouble speaking English? Also, why does this guy keep fumbling
    around the damn phone like it’s foeign to him? These are things I’d like to know.

  5. You guys realize that voice plan on cell phone are going away (eventually). They have too. With VOIP why bother with voice call billed per minutes when you can (currently) have unlimited data plan. Just imagine a cell phone Data only that cost $30 per month.

    AT&T;and friends are going to have to make changes, they will not survive on $30 per month data plan.

    Take note, unlimited data plan will go away and will become as expensive as voice plan. It will be per Gigabytes plan and the monthly bill will be back to what we have today…

  6. Grand Central now that is interesting, I thought the A4 was supposed to be single core, if so why would they need Grand Central? Perhaps things aren’t quite what they seem or otherwise surely some lateral thinking is required..

  7. Why do I need a cell phone any more? Tell me if I am wrong here. I buy a iPad 3g version and get ATT $15 per month connectivity. Then after iPhone OS 4 is out, I have skype running constantly and use it exclusively for phone calls. I have a bluetooth headset that pairs with the iPad. No more paying for minutes and my monthly ATT cost just went from $100 to $15. Where is the flaw in my logic?.

    your comment reminds me of an old joke.
    What do you call a person who can speak 3 languages? trilingual
    What do you call a person who can speak 2 languages? bilingual
    What do you call a person who can speak 1 language? english
    So how’s your Polish?

    why do so few people speak English. Because England is a tiny nation where I live. We leant you a few of our undesirables a long time ago and so you too spea English.
    Apart from a bit of pigeon French I cannot speak any other language.
    I have tried to speak Poish as I have many Polish friends nowadays but their language is incredibly complex. But, do not mock any Pole who cannot speak English at this moment in time because one I know who can now speak good English could not when I first met him but he could speak fluently in FIVE other languanges at that time. Contrary to what the Germans thought during the second world war ( and what a nitre dame fan once said to me at an American football match I was at) THEY ARE NOT dumb polacks.

    Spot on, and thank you for sticking up for the intelligent part of society.

    No flaw. Just pay attention to “Obviously.” He’s right: the fees will float back up to today’s prices because the market will bear those costs. The first casualty will be the ‘unlimited’ plans. Those plans will disappear as soon as people attempt to use them.

  11. @theloniousMac,

    I gave up my landline about a year or so before the iPhone came out. I never looked back. Although one thing that kind of sucked was that I had just purchased a phone system for my Mac that was awesome…it provided visual voicemail, auto-imported into iTunes, sent email attachments…really cool stuff, but it came just as the need for a landline was dying 🙁

    Last month I rented a SIM from iPhoneTrip.com and traveled all around Europe. It gives you unlimited 3G data, but you pay for voice…unless you VoIP. They include a handful of free minutes each week, but I found myself never using any of them. I Skyped, emailed, SMSd, etc… Google Voice was very helpful too because I just forwarded my normal cell number and then received emails whenever someone left a message.

    With Skype and iPhone 4.0, I’m definitely going to remain on the lowest minute plan available, and will be looking to kill it soon.

    it’s not my English that’s the problem it’s the fact that my bloody iPhone keeps thinking it knows what I am trying to say when in actual factvit bloody well doesn’t. So there! Ya boo sucks!

  13. Grand Central Dispatch is part of iPhone OS 4? That’s very cool for the (multi-core) future of iPhones, iPod touches, and iPads. That is, unless the future is already here and the “4” in A4 has a deeper meaning.
