iPhone OS 4.0 Announced

Today, Apple announced the upcoming iPhone OS 4.0 the new big release of the popular mobile operating system. It's new features mainly come from jailbroken features like Stacks, Backgrounder, and Winterboard.

Here's the list of some of the new features:

-Multitasking
-Home screen wallpaper
-Folders for apps
-Game Center (the new official social gaming center)
-iBooks (the eBook app and store from the iPad)
-iAds (a new way of inserting ads in apps and getting 60% of the income from them)
-Unified Inbox in Mail
-5x digital zoom in the camera
-Bluetooth keyboard support
-In-app SMS

Unfotunately (for some people including me) this release won't be compatible with the first generation iPhone or iPod Touch. Also, multitasking won't work for iPhone 3G and iPod Touch second generation. The devices that will have all of those features will only be the iPhone, the iPod Touch third generation, the iPad, and probably the upcoming devices that are yet to be announced.

The OS is scheduled to be released in summer for iPhone and iPod Touch and in fall for the iPad.
