A chinese website claims that it was able to test a beta version of iOS 6 (build 10A5316k).
Bad news for all owners of the first generation of iPad, as it apparently wouldn't be supported, but nothing has been confirmed for now. It would be also the same for the 3rd generation of iPod touch while the iPhone 3GS, which is still sold by Apple, would be supported.
We should have all the answers tomorrow since the beta versions of iOS 6 and Safari 6 will most likely be made available just after the keynote.
