Just a day after releasing iTunes 10.3 to support some early iCloud features such as automatic downloads and access to previously purchased content, Apple has released iTunes 10.3.1, to fix critical issues in the application. The documentation accompanying the release and Apple’s support page merely offer the same information as found with the original iTunes 10.3 release, providing no word on exactly what is addressed in what is presumably a minor bug fix update. It is believed to fix the “unknown error (-50)” some users would get while syncing iOS devices. No fixes were found as of this writing, but there’s no reason not to get this free update. This update comes two days after the Cupertino company unveiled iTunes 10.3 at WWDC, which includes support for “iTunes in the Cloud”, new online technologies that allow users to have all purchases synced to up to 10 devices on the fly, as well as to individually download past purchases, including apps, songs and e-books. These features are part of iCloud, which will ship in the fall, including photo syncing, and the ability to stream changes to documents on the fly within iWork. Apple has also announced iTunes Match, a $25-a-year service that helps user convert their own songs into 256-Kbps iTunes Plus quality AAC files for free. Steve Jobs couldn’t have said it better: Today it is a real hassle and very frustrating to keep all your information and content up-to-date across all your devices, [...] iCloud keeps your important information and content up to date across all your devices. All of this happens automatically and wirelessly, and because it’s integrated into our apps you don’t even need to think about it—it all just works. Download iTunes 10.3.1: You can get iTunes 10.3.1 from Software Update, if you haven’t already, or iTunes download page. If you’re running iTunes 10.5, which you can obtain from Apple’s developer site, if you’re a registered member, please don’t install iTunes 10.3.1, or else your iOS 5 device will no longer work.
