No iOS 6 for Original iPad and Third-Gen iPod Touch?
In the course of Apple's history, the company has been known to drop support for its older line of products. With this being said, a rumor saying that iOS 6, alleged to be announced during the upcoming WWDC 2012, will not support the original iPad or third-generation iPod touch isn't all that surprising.
The Verge - A forum post on WeiPhone claims to have a full list of the upcoming developer releases of both iOS 6 and OS X 10.8 Mountain Lion, and the aforementioned devices are conspicuously missing.
Needless to say, the information is to be taken with a pinch of salt until it has been announced officially at the event.
