Similarly, if it was the case that the heaviest users migrated from the 3G or 4 or Nexus One to the 4S, they'd probably mention it. But it sounds like they're saying that data usage is going up both on a per-user and total basis.

Historical data yes. But how are they going to figure out that a previous iPhone 3G/3GS/4 or Nexus One user is now using an iPhone 4? Would privacy laws allow for them to get individual customer data and know exactly which customers upgraded their phones?
