Apple released the beta version of the much awaited update for iPhone, OS 4 to iPhone Developer Program members. The beta release includes an updated Software Development Kit (SDK) with over 1,500 new Application Programming Interfaces (APIs) and over 100 new features that will be available to iPhone and iPod touch® users this summer. New features include Multitasking for third party apps; Folders to better organize and access apps; improved Mail with a unified inbox, fast inbox switching and threaded messages; enhanced Enterprise support with even better data protection, mobile device management, wireless app distribution and more; Apple’s new iAd mobile advertising platform; and iBooks, the delightful new ebook reader and online bookstore recently debuted on the iPad™.
This update will be free for iPhone users and Paid for iPod Touch Users(Bah!) This update will NOT be available to first generation iPod touch users (Sorry folks..!) It will support iPod Touch 3G & iPod Touch 2G (released late in 2009).
Hope, i am entitled for this update, as i bought my iPod Touch 2G in late august. Anxiously waiting for the final release.
