Apple just release of iOS 5 beta 3, Apple has also seeded the third beta of iTunes 10.5 beta 3 which is a major requirement if you plan on restoring your iPhone, iPad or iPod touch to iOS 5 beta 3.
iTunes 10.5 beta fully supports the features and services of iOS 5 beta 3, without which it would be completely useless. To start off with, iTunes 10.5 beta 3 is a very necessary download in order to get your iPhone, iPad or iPod touch up to speed with iOS 5 beta 3, and to say the least, iTunes 10.5 is the only way through which you can restore to the newest beta of iOS 5.
The previous release of iTunes 10.5 beta 2 and iOS 5 beta 2 enabled the most awaited Wi-Fi sync feature on all iOS devices, which enables users to sync their iPhones, iPads and iPod touches with their PC or Mac without any cables attached, and that too over Wi-Fi. The current release of iTunes 10.5 beta however doesn’t bring that much over the previous beta, except that it carries a lot of bug fixes and makes iTunes 10.5 beta a lot more stable to run on your PC or Mac.
