AllThingsD reports on findings of a survey by Consumer Intelligence Research Partners which investigated where iPhone owners purchased their device. The found that the breakdown of retail vs online sales was 76 percent retail vs 24 percent online. Of that 76% from retail stores, the breakdown showed that Best Buy was almost as big as Apple's own retail stores as a point of sale: Carrier stores are clearly the dominant point of sale for most consumers, but Best Buy's presence has also proven to be a significant location for iPhone sales.
