Electronista points out that Flickr's Camera Finder is now showing that the iPhone is the most popular camera used for photos uploaded to the image sharing site. After approximately six weeks of trailing just behind the Canon EOS Digital Rebel XTi, the iPhone has surged into the lead with a spike in activity over the past several weeks.
Flickr notes that the data is taken on a daily basis and measures the proportion of members who upload at least one photo from a specific camera on any given day. Because not all camera phones include model-identifying information in their metadata, such devices are under-represented in Flickr's data, although model identification is possible for approximately two-thirds of images uploaded.
Apple's iPhone has long been the most popular of the identifiable camera phones for Flickr uploads.
