iOS 4.2

Some iPhone owners who jumped to install the iOS 4.2 firmware update yesterday were greeted with an unwelcome surprise. Media including music, audio books, podcasts and videos disappear after the update is complete. iTunes still displays the storage space occupied by the media files, but they are nowhere to be found on the iPhone.

Opening the iPod app simply says "No Content" and re-syncing with iTunes does not bring back the media library! Apparently something was overlooked by Apple, but lucky for iPhone owners the bug fix is quick and easy. Your music files are hidden but still stored on the device. Don't restore your iPhone or take drastic measures, just follow these simple steps:

Apple officially released the iOS 4.2 update today at 10AM PST. iPhone 4 owners get a special surprise in the latest operating system, free Find My iPhone service. The feature makes it possible to locate your lost iPhone using maps on the web. Previously the service required a paid MobileMe subscription to use.

iPhone 3G owners are anticipating significant increases in speed and performance with the latest fixes and optimizations included in iOS 4.2. This version of iOS is the first to run across all recent iOS devices and will hit the iPad and iPod touch today as well. Several new features will come to the iPhone.

Evidence is mounting that Apple plans to release iOS 4.2 to anxious iPhone and iPad owners at 10 AM PST on Friday, November 12. iTunes 10.1, which hasn't been released yet, will be required to install the iOS 4.2 firmware. All indications are that Apple will launch iTunes 10.1 and Mac OS X 10.6.5 as early as Wednesday to prepare for the iOS 4.2 public release. The golden master of iOS 4.2 has already been seeded to developers and is not expected to change in the public version.

German blog iFun found evidence (above) that Apple plans to push carrier updates to wireless service providers on November 12. This date matches with inside infomation from an anonymous AT&T employee revealed by MacStories. The source also stated that Apple was delayed in its release of iOS 4.2 due to a bug discovered by AT&T testers. iOS 4.2 was originally slated for release on November 2, however an error in the display of Japanese characters required a fix from Apple.

iPhone 3G users were disappointed when Apple's iOS 4.0 made their devices all but unusable due to sluggish performance and short battery life. The iOS 4.1 update was a step in the right direction, with iPhone 3G owners reporting that Apple had made significant improvements. With the release of iOS 4.2 coming any day now, many are wondering if upgrading the firmware on their devices will speed things up even further or lead to more problems.

Apple has released the golden master of iOS 4.2, which is the last version that goes to developers before public release via iTunes. The iPhone Blog has thoroughly tested iOS 4.2 on the iPhone 3G and they have revealed that iOS 4.2 runs pretty smoothly in a video demonstration.

Two months from now Apple will release iOS firmware 4.2 for the iPhone 4, iPhone 3GS and 3G. The new operating system unifies the iOS mobile operating system and iPhones and iPads (with the exception of the original iPhone) will finally be running the same version. Several new features are coming to the iPhone with the iOS 4.2 release.

The beta version was released to developers by Apple today. One new application is the multitasking Print Center. Print Center will allow the iPhone 4 and iPhone 3GS to print wirelessly with AirPrint. As long as a Wi-Fi network and a compatible networked printer are available, photos and other documents can be printed directly from the iPhone.
