Seems like the new version of iTunes and MacOSX are out, it’s only a small update for both. For the OSX it is just an update so that it is compatible with iOS 4.2 AirPrint functionality.
The new iTunes 10.1 has the same update and a few minor bug fixes, but otherwise it’s main update has been, so that iTunes support printing for iOS 4.2.
iOS 4.2 is also due it’s release on friday 11th November, which is a major update for the iPad, as it brings it up to date with other iDevices, whereas the update for iTouch and etc, don’t have any useful features.
For people worrying about a jailbreak on their device, do not worry about this, as greenpois0n and limera1n already supports it, and a new jailbreak will come out soon, along with an unlock for the phones. Also if you are already jailbroken, then please do save your SHSH’s blobs, if you are updating to 4.2.
Both of them haven’t been released yet but should be out in a few hours
