Natuba is a new social photo site geared toward iPhone users. Natuba allows you to upload your photos from your iPhone to their site. To do this you email your photo to the email address they provide. You are then able to view your photo and share it with others.

Now this is already offered by Flickr and there are a few applications that automatically upload any photo you take from your iPhone to your Flickr account. It all depends upon which service you think will better fit you.
