Comprehensive iOS 4 Walkthrough ☀

This is the most comprehensive iOS 4 walkthrough I have seen to date:

iOS 4 (previously iPhone OS 4 or iPhone 4.0) continues Apple’s relentless yearly mobile OS update cycle. If 2007 was the mainstreaming of the multitouch user interface, 2008 all about the App Store, and 2009 was filling in the feature list, then iOS 4 promises to be… well, that’s why we’re here.

Back on April 8 at the sneak preview event, Apple promised 7 “tent-pole” features and 100+ general user features overall, along with 1500 major new API for developers. We’re going to walk you through the ones that matter most.

All your questions about iOS 4 should be answered after reading the article, which incidentally is based on the iOS 4 GM that developers have had access to since about day 1 of WWDC. Some minor tweaks may take place between the GM and final release, but overall the operating system should mostly contain everything seen in the walkthrough. (via DF)
