The details come from a list of links to the Apple Developer Connection website for an iOS 6 beta build labeled "10A5316K." The links are not active, as Apple has yet to formally announce iOS 6 or release a beta to developers.
The full list of links to Apple's developer site were provided to AppleInsider on Saturday, but the links are not active, so they could easily have been faked. The links appear to have originated from the Chinese website WeiPhone.com.
The provided links give a "Session Expired" page when accessing them is attempted. Changing the links slightly sends users to a page that instead reads "Access Denied."
The full list of devices claimed to be supported by the iOS 6 beta are the iPad 2, and third-generation iPad; the iPhone 3GS, iPhone 4, and iPhone 4S; the fourth-generation iPod touch; and the second- and third-generation Apple TV.
If the links are legitimate, they would suggest that Apple plans to drop support for the third-generation iPod touch and first-generation iPad with the first beta of iOS 6.
Also included among the list of links is an unannounced Safari 6. They include a developer preview for OS X 10.7 Lion, and a separate uninstaller.
The appearance of iOS 6 at this week's Worldwide Developers Conference was revealed last week, when Apple began hanging banners inside Moscone West in San Francisco, Calif. The conference will kick off on Monday.
iOS 6 and other products are expected to be officially introduced by Apple in a keynote presentation on Monday at 10 a.m. Pacific, 1 p.m. Eastern. AppleInsider will have full, live coverage of the event.
