Apple invented the non-standard "viewport" meta tag and gave guidelines on how to use it [1]. The article that has popularized the term RWD mentions iPhone four times [2]. For me it is obvious that RWD started from the iPhone, but maybe our viewpoints (or viewports) differ.
I believe you are right, but on a different level. Iphone started the mobile revolution which inspired other phone builders. When earlier we used build m.website.tld websites, the bigger screens from Iphone-inspired smartphones allowed us to use the same website, with mediaqueries.
Maybe it's because I'm Europe based, but we didn't really develop for iphones initally.
