Apple Accepting iOS 4 Apps for Approval

Thursday June 10, 2010 7:42 pm PDT by Arnold Kim

Apple has started accepting iOS 4 applications ahead of the June 21st release of iOS 4. Formerly called iPhone OS, iOS 4 is the rebranding of the operating system that runs on the iPhone, iPod Touch and iPad. Version 4 introduces many new features for developers and users that may require modifications to existing apps for full compatibility. Some of the features include:

- Multitasking
- Folders
- Improved Mail App
- Enhanced Enterprise support
- iAds
- iBooks

Apple claims there are over 1,500 new Application Programming Interfaces (APIs) available for developers. iOS 4 will be available to iPhone and iPod Touch owners for free on June 21st. iOS will not run on the original iPhone or 1st generation iPod Touch and will only run with limited features (no multitasking) on the iPhone 3G and 2nd generation iPod Touch.

I really hope iOS lives up to the expectations... It has a lot of them. It really needs to catch up to the rest of the mobile world.

Lol, and here we go.

I'm looking forward to ios 4. I don't know if I'll be buying an iPhone 4 (recently having a lot of trouble with AT&T so not sure I want to lock myself in for another 2 years with a high EFT), so I really hope it runs well on the 3gs (unlike os 3 on the 3g).

It's running beautifully on mine.

Does anyone know what some of the book APIs are that are included in "over 1500 new APIs"? (Besides the ones for multitasking)

As a developer, I'm still trying to gracefully figure out how to use iOS 4.0 features (mainly multi-tasking) and support the new Retina display without flat-out requiring iOS 4.0 and leaving out all 3.x users to dry. It leads to a major headache in bug testing.

What I'm trying to say is, for users still on 3.x, don't upgrade immediately to apps that say they support iOS 4.0. I have a feeling a lot of apps are going to crash because of some obscure bug that cropped up in their code (it happens). Particularly, trying to deal with running out of memory on the device and having an app forceably quit on itself.

Just a warning from one developer to the public. :)

And here I am, stuck with a 1st generation iPod touch. I'm also not upgrading until the 4th generation, hopefully with almost all the features of the iPhone 4.

I'd like to know the percentage of users who own iDevices that can't be upgraded to iOS 4. :confused:
