Flickr’s new iPhone web interface = AWESOME (with screenshots!) (Tiny Screenfuls (JoshB)) by Josh Bancroft
Saw word from John “Daring Fireball” Gruber tonight that Flickr finally launched an iPhone optimized web interface. Finally! 
Of course, I had to check it out right away, and I agree with John - it’s great. Possibly the best iPhone web interface I’ve seen. Really nice. There’s no way to upload photos from the site (though they do point out that you can upload via email, which I’ve been doing from the beginning from my iPhone, and it works really well). But that’s about the only thing I can see that’s missing.
Update - What Doesn’t Work: The things that work on the desktop but don’t work on the iPhone version are basically the parts of the site that use Flash - the Uploadr, the Organizr, the Map, and Video playback (you can still see video pages and their comments, you just can’t play the videos). Oh, and Slideshows. Everything else works. I see this as one big benefit of all the work Flickr did a long time ago to move as much of their interface as possible into Ajax and javascript, and away from Flash (which doesn’t work on the iPhone, and likely never will).
To check it out yourself, go to m.flickr.com on your iPhone or iPod Touch. I’m sure the other methods you can use to trick sites into thinking you’re using an iPhone will work, too. There’s even a nice iPhone Home Screen icon if you want to save a bookmark to it there, and launch it from the Home Screen.
I took a bunch of screenshots. Here they are, in no particular order:
