Multitasking, sort of
Yes, finally, iPhone OS supports multitasking! The feature allows you to run multiple apps at the same time and easily switch among them.
However, in order to reduce consumption of system resources, the background processes are limited to 7 classes: music, VOIP (read: Skype), GPS, Push notification, Local notification, and Fast app switching.
Don’t expect the multitasking works like you have on your computer.
Now you can group iPhone apps together into a folder. Example: put all game apps into a game folder. Folder name is auto generated but you can rename it. You can also change the wallpaper of the iPhone folder.
Better Mail app
Mail for iPhone now use unified inbox so that you can have multiple email accounts delivered into one inbox. Thread messages is integrated.Open email attachments in third-party app. Also, iPhone OS 4 now support multiple Exchange accounts.

My two cents
iPhone OS 4 is a killer-wannabe!
- iPhone will support Multitasking. The advantages of other smartphone OS over iPhone OS is lesser.
- iBooks on iPhones & iPad is threatening Amazon.com’s Kindle.
- The Game Center is a challenge to PlayStation Network and Xbox Live.
- The enterprise features is a threat to Research in Motion (BlackBerry), which is popular among business users.
- iAd, is the Apple’s answer to Google’s mobile advertising.
Wow, and wow!
