What's New in iOS 5
iOS 5 might be the most popular version of Apple's mobile OS yet. When Apple released it as a digital download through iTunes on Oct. 12 the heavy demand almost crashed Apple's servers.
Available for the iPhone 3GS, iPhone 4, iPhone 4S, and all iPads, this update includes more than 200 enhancements for a reasonable price--it's free. This visual tour focuses on 11 major enhancements and four new apps introduced with iOS 5.
Finally, Apple has added a feature to perform over-the-air updates on the iPhone, iPod Touch, and iPad. This will allow Apple to rapidly deploy minor updates and maybe even major ones. It supports the cloud concepts that Apple seems to be embracing at a rapid pace.
