WordPress have introduced an Open Source app that lets you write posts, upload photos, and edit your WordPress blog from your iPhone or iPod Touch. With support for both WordPress.com and self-hosted WordPress (2.5.1 or higher), users can now write and manage their blog on the go.
Download from the iTunes AppStore.
The interesting bit is the solution to prevent data loss when receiving a call. WordPress for iPhone will recover your post after ending the call. You can take pictures on the phone and blog them instantly, iPod touch users are limited to pictures from the photo library.
See pictures of the app in action in the gallery.
