iPhone OS 4.0 – The Deets

What do you need to know about iPhone OS 4.0? Here you go:


  • Pulls up a dock on the bottom of the screen when you double-click the home key. The dock displays all of your programs that are “running.”
  • Programs aren’t really “running” in the background. Instead, Apple gives apps access to 7 actions to essentially multitask. These are: Background audio, VOIP, Background Location, Push notifications, Local notifications, Task completion and Fast app switching.
  • Apps frozen still essentially, so when you boot them back up, it’ll return to normal state – great for games, I’d imagine.
  • Background audio now allowed. Pandora runs in the background and can use iPod’s lock screen controls.
  • VOIP good to go. You can leave on Skype and it acts just like a regular phone call, but with a red bar on the top when you navigate away from Skype.
  • Task completion – finish uploading a photo to Flickr (per their example) but navigate away from the app
  • Push notifications from apps – That Flickr reminder could in theory pop up if there’s a problem uploading a file.


  • You can put apps in folders now to organize them. That way you can organize these folders with multiple items inside of them, giving you more room for more apps.
  • Folders can be installed on the dock as well.
  • The image of a folder contains smaller images of the apps inside.
  • 2160 Total Apps available per phone


  • Background for all app screens, just like the iPad.
  • Can be different for Lock screen and app screen


  • Unified Inbox (thank god!)
  • Multiple Exchange accounts allowed
  • Follow threads by tapping on “>>” icon
  • Fast inbox switching for going to a dedicated inbox if need be
  • Open attachments with third party apps from the app store


  • Support for iPhone
  • Wirelessly syncs books and bookmarks from iPad


  • Mail encryption
  • Wireless app distribution for local companies (You host the app on your server, distribute to clients)
  • Exchange Server 2010
  • SSL VPN Support

Game Center

  • Social gaming network
  • Invite friends, do matchmaking, leaderboards. Think XBox Live for the iPhone


  • Mobile advertising for the iPhone OS
  • A way to fund free apps, that is “better” than current models
  • Jobs says that people spend 30 minutes in apps each day
  • Apps are interactive and keep the user inside the app they’re currently in
  • Apple hosts ads on their servers, does a 60/40 split (Developers get 60%)
  • All coded in HTML5
  • Tap the banner, and ad pulls up. Then click the “X” icon at the top left corner of the ad, and you’re back in the app
  • Games, maps and videos can be in the ad, making it completely interactive
  • In-ad purchasing as well

The Miscellaneous Stuff

  • Bluetooth keyboards for iPhone
  • Tap to focus for video
  • Calendar access to developers
  • In-app SMS (brilliant)
  • Half-curl page transition – like in iBooks


  • iPhone 3GS and 3rd Gen iPod Touch get everything this summer
  • iPhone 3G and 2nd Gen iPod Touch get some but not all features this summer (And they’re not including multitasking)
  • iPad Fall 2010
