WordPress iPhone
Check out the official site for the WordPress iPhone App, which was announced on July 10th, and expected to be available in the App store any day now.

We at vunitemedia have a lot of sites on WordPress, and are iPhone users; so we are really looking forward to a potentially neat iPhone App.

… the first Open Source app that lets you write posts, upload photos, and edit your WordPress blog directly from your iPhone or iPod Touch. With support for both WordPress.com and self-hosted WordPress (2.5.1 or higher), users of all experience levels can get going in just seconds.
