Prepare for the iOS 4 update for your iPhone.

Jun 21, 2010

To prepare yourself for the new iOS 4, backup your iPhone 3G or 3GS with iTunes 9.2. This version of iTunes is iOS 4 compatible and allows the backup of the folders which iOS 4 has.

To recap on the new features for the iPhone 3G and 3GS, check out Apple’s iOS 4 site.

iPhone 3G owners need to be aware that some new iOS 4 features are not available on the iPhone 3G hardware.
