Apple on Wednesday made good on its promise to push out the release build of iOS 5 to consumers around the world. The new software is available for download immediately, and iTunes 10.5 is required in order to install the update. Owners of Apple’s iPhone 4 (GSM and CDMA), iPhone 3GS, iPad 2, iPad and third and fourth-generation iPod touch handhelds have access to the new build, while owners of earlier devices will not be able to install the update. iOS 5 includes more than 200 new features such as a revampedÂ notifications system, iMessage, built-in Twitter integration, Newsstand and more. Apple also released OS X 10.7.2 with iCloud support and two new iOS apps on Wednesday: Find My Friends, which can be downloaded by visiting iCloud.com on your iOS device, and AirPort Utility.
