According to the official iPhone Human Interface Guidelines recently published by Apple, only one iPhone application may run at a time, and third-party iPhone applications will not be able to run in the background, posing a potential challenge to developers. “Only one iPhone application can run at a time, and third-party applications never run in the background,” the document states. “This means that when users switch to another application, answer the phone, or check their email, the application they were using quits..."

Think John Gruber at Daring Fireball spotted this first. I'm probably missing something in thinking about this, but this sounds potentially *very* lame to me. If apps don't remember their last state / where you were at when you switch away from them, then that is suckerama I think.

Surely, iPhone platform is going to handle this better than the dinosaur Palm OS ...

Hmm... sounds very limited. What with the iPhone running OS X, I don't see why Apple wouldn't take advantage of that... interesting.

Don't you go stealing my signature, boy! :p

Even though it is a watered down version of OS X, Steve stated last year that it still allows for all apps to run in the background.

Yes, but we just got told during yesterday's event that it runs the real deal OSX kernel etc. Besides which, Windows Mobile does multi-tasking, and has done for several years ...

Hopefully they will figure out a way so that it can save your state in some sort of database on the phone when you hit the home button, or a text/call comes in.

Whatever people decide to develop. Anybody can download the SDK, and anybody can have their apps put on the App Store, so.. other than things Apple prohibits (SIM unlocks, etc.) the possibilities are endless.

if this is true I can see myself buying the Sony Ericsson xperia x1 when it comes out or even going back to my nokia n95-3 or the n96 when its released. Major bummer if its true

I can surf the web now and listen to music.....I will NOT be able to do that soon? Is that what you're saying..?
say you are playing a game and you get an IM on AIM or you want to check email. from what I understand, switching to one of those apps from the game you are playing will kill that game, it won't stay running in the background and as a result not remember what point of the game you were in. you can still surf the web and listen to music, but 3rd party apps will not be allowed to run in the background while others are running from what I understand.

idunno sure hope not. that's just what i gather from reading this thread and the article. Surely they don't expect to compete with the WM, BB, and Symbian platforms if it is not going to be decent at multitasking. Maybe that's another area where Jobs is worried about battery drain. That was a lame excuse for 3g and I surely wouldn't buy it for this

I hope we see an MMS app through the SDK but who knows. Apple will probably handle things like that delicately as it seems AT&T has a hand in the lack of MMS as well. Apple doesn't want to burn any bridges with AT&T I'm sure.

The apps will definitely be able to save state, so to the user it should be transparent. You won't even know the app closed.

Where this really matters is in apps that need to keep running in the background, or at least run a daemon. I would hope they aren't completely locked out, including daemons.

I might buy a Mac just to be able to use the SDK....

I might buy a mac for it if there was a cheap used mac somewhere. I have almost never used a mac before though :-þ

To be frank if I bought one it would be a Macbook, or Macbook Pro--but I'd mostly use it to run Windows. I usually get a new laptop every year and now is about the time.

Oh yes, one thing to keep in mind is that you need an Intel Mac for the SDK.

Yeah it would be very lame if the third party applications just quiet if you went and had to answer a phone call. I was looking forward to some solid games that have the ability to save your progress.
