Last month, we highlighted a number of device restrictions regarding Apple's high-profile features for iOS 6, noting that many of them would not be compatible with the iPhone 3GS while smaller subsets would not be supported on the iPhone 4 and iPad 2.



But with yesterday's release of iOS 6 Beta 3 for developers, Apple has improved feature support for the iPhone 3GS, adding shared Photo Streams and VIP mail filtering. The change was noticed by a number of iPhone 3GS users, and Apple has confirmed the removal of those restrictions on its iOS 6 preview page.

While the iOS 6 preview page previously contained eight footnotes outlining various restrictions on features, that number has been reduced to six following the release of iOS 6 Beta 3. The two removed footnotes include:

- Shared Photo Streams requires iOS 6 on iPhone 4 or later or iPad 2 or later, or a Mac computer with OS X Mountain Lion. An up-to-date browser is required for accessing shared photo streams on the web. - VIP list and VIP and Flagged smart mailboxes will be available on iPhone 4 or later and iPad 2 or later.

The fact that iOS 6 is compatible with the iPhone 3GS at all marks a significant step for Apple, as the device was also the minimum requirement for iOS 5 released last year. But with Apple still selling the three year-old device, the company apparently felt that it needed to bring many of the new features of iOS 6 to the iPhone 3GS and is still working to add as many as it can within the constraints of the older hardware's capabilities.
