Being European I have zero interest in this, however.....
If it's not been mentioned already (I'm not trawling through all 4 pages so far) aside from the fact Apple's ad people are in-house, the one thing I can confirm which casts another major doubt on the credibility of this story is that Landor is NOT an ad agency.
They are a legendary brand ID consultancy, who designed the Fedex and 'eco' BP logos amongst many others. They used to be part of Y&R and now WPP since the merger almost a decade ago. They would have no part in any ad campaign beyond designing new branding. I suspect Verizon may well be tendering for a complete brand overhaul of their own brand ID and someone's seen a pitch concept which uses the iPhone (non-existent on that network) as a hook, drawn the wrong conclusion, and got a wee bit overexcited.
If this does go to an ad agency, it would go to Landor's siblings, one of the big WPP houses like JWT, O&M etc. on Madison Ave. The industry would have got wind of it a long time ago if true, NDA or no NDA, gossip travels fast.
Ergo, it's nonsense.
