couple of hours ago by apple.Although iPhone 4G will be in stores on thursday (which has been already extensively preordered too), this update is still available for the existing iPhone owners to take advantage of the new software features.
The new iOS 4 is free for update. It’s compatible with iPhone 3G and 3Gs and iPod touch (second and third generation). However multitasking will work only with iPhone 3Gs and third generation iPod touch.
The exciting new update of iOS, 4.0 has more than 1,500 backend changes and many additions to API which will make the app development for iPhone alot easier and feature rich process resulting in much better and advance apps on these devices.
Some of the highlights of the iPhone iOS 4 are:
