WordPress for iOS

More than writing and publishing quick posts on the go, WordPress' iPhone app offers the discerning user a powerful publishing tool for uploading photos from your existing library or from a quick camera shot. You'll be able to work on multiple posts, saving drafts locally to your phone, and a preview function. HTML links are fully supported. While we don't begrudge WordPress for iPhone's emphasis on function over form, it is missing some crucial things like copy and paste (that's Apple's fault), and comment moderation that would make this a stellar, fully functional app.
