WWDC 2010: iOS 4
June 7, 2010
As we just found out moments ago, iPhone OS 4 is no more. Instead, it will be named "iOS 4". Not much more is known about it, but it has support for Retina Displays, such as the one found on the new iPhone 4. iOS 4 is entering the Golden Master edition today, meaning it will be released soon.
Check back soon for any more information we learn!
Update: The release date is June 21! iOS 4 will work on the iPhone 4, 3GS, and 3G, as well as the iPod Touch 2nd and 3rd generation.
