I don't want to get bogged down either...but you're wrong...
No. You're still wrong.
You're assuming everyone buys their iPhone at launch.
If someone were to walk into an Apple store on September 19, 2011 (one year before iOS 6 was released) and ask to buy the latest and greatest, most current iPhone, they'd walk out with a 4. The 4S wouldn't be announced or available for a few more weeks.
Just because the phone had already been available for 16 months doesn't change anything. With no newer model announced of available, it was still the latest tech and Apple gladly sold it as such.
