Apple officially released the final iOS 4. It’s still called iPhone OS 4 in the SDK, but both names refer to the same code/piece of software. The iOS 4 GM (Golden Master) was made available to developers 2 weeks ago and should be exactly the same code as yesterday’s official release. I’ve been testing iOS 4 on my iPhone 3G for 2 weeks now and reported some of my experiences in my iOS 4 review on iPhone 3G.
