On Saturday, Flickr jumped into the murky pools of the App Store with
an official native client. The application’s certainly eye-catching: upon logging in, it’ll show you a slideshow of your contacts’ recent photos, zooming in-and-out in Ken Burns-style. You can search, browse (by sets or tags), view recent activity, and, of course, upload pictures snapped with your iPhone. Uploading lets you add tags (including browsing your existing collection of tags), description, and even your current location, drawn from the iPhone’s Core Location services.
The Flickr application is free and requires an iPhone or iPod touch running at least iPhone OS 3.0.
