The iPhone will come out in July (or whenever) irrespective of you knowing two months in advance its specs. Nothing changes. Nothing will be hidden. There is no "public interest". It's just idle curiosity, and it's not journalism to pander to it to the extent of participating in a very dodgy transaction.
I personally don't agree with this, and you may not either, but that doesn't matter.
Reference? The ones I have been aware of have been very narrow, and there have been many public cases of the opposite (such as the recent Max Mosley case in the UK).
Generally the law seems to take a line similar to that of Wikipedia - that "public interest" means "general welfare". Note that this does not mean you can't publish details about the sex lives of celebrities, but you can't use public interest as a defense if you have participated in a crime to do so.
But it would be hard to argue that this story was presented with the aim of improving the public welfare, as you might if the contents of some confidential government documents were reported or publicized.
