Good news for obsessive bloggers everywhere: our friends at iPhone Matters recently reported that WordPress is set to release a native iPhone blogging application. Of course, many blogging clients are already accessible from Safari, but the convenience of a native application is truly invaluable. Matt Mullenwag, CEO of WordPress, confirmed that the company would be coming out with a “built-in” iPhone WordPress client soon.

As you may remember from previous posts, TypePad also plans to release a native iPhone app. Six Apart—the company that owns TypePad—announced plans to develop a native TypePad mobile application for the iPhone with the (relatively) recently released Software Developer’s Kit (SDK). As you may know, TypePad and Movable Type users already benefit from an optimized iPhone blogging interface through their device’s web browser; however, a native TypePad iPhone app. promises to make usage even friendlier.
