Yesterday at WWDC, Apple introduced the next major version of its mobile operating system iOS5 with more than 1500 new APIs and 200 new features.
iOS5 includes a new Notification Center, a new Camera app, more info on the lock screen, Wi-Fi sync with iTunes and much more. Readers can read this article to know all about iOS5.
iOS5 will support iPhone 3GS, iPhone 4, iPod Touch 3rd Gen and 4th gen along with the iPad 1/2. For the general consumers, iOS5 is expected to be released sometime during this fall, presumably with a new iPhone.
However, Apple has already released a beta of iOS5 for developers to develop apps on. The beta can be downloaded from here. Only developers who have a developer account with Apple can download the beta.
General users, who are interested in trying out iOS5 on their iDevice, should ask some iOS developer for help. If a developer registers a UDID of an iDevice, then he or she can legally install iOS5 on their device.
