I couldn't see any post in this thread explicitly saying that iTunes 10.1 is needed in order to install the GM but there are lots of posts telling people to to download 10.1 beta 2 and various links for where to get that so is it the case that iTunes 10.1 is required in order to install the iOS 4.2 GM? If this is the case then presumeably it isn't enough for Apple to decide that the 4.2 GM is OK to release, they'll also have to decide that iTunes 10.1 is also good to go and take that out of beta as well.
They can't release a new version of iOS that requires a beta version of iTunes to install can they? If iTunes 10.1 isn't ready then would it be a case of people still running 10.0.1 wouldn't be offered the iOS update for their device, even though Apple had officially released it, and it would only be when iTunes 10.1 comes out of beta that the update is seen?
I'm a bit confused, and guessing a lot here, but I'd like to understand what the real situation is.
