So u mean to twill me, 4.2 beta is working flawlessly and we still have to wait a whole month and a half. This is some ********.
Oh for gods sake!
There are still issues in the basic os and apple need to do wide scale testing to identify, fix and test bugs, hence the beta release. At the same time developers need time to upgrade and test their apps, again accomplished via the beta. And some functionality, specifically airplay and printing, clearly isn't ready yet.
Does that make it clear why we have to wait a while? Honestly, a little patience wouldn't go amiss here.
