WordPress has developed an application allowing you to post to any of your blogs through the iPhone. The screenshots below show just enough to post your photos and blog on the go but the description below shows that it has a lot more capabilities. Here is a description from the iTunes store.

Robust but simple to use, the WordPress for iPhone Open Source application allows you to create and edit content on your WordPress blog(s) with support for offline use. The app includes the following features:

• Support for WordPress.com blogs and self-installed WordPress blogs (version 2.5.1 and higher)
• Embedded Safari for true previews of posts
• Full support for tags and categories
• Photo support for both camera pics and library photos
• Support for multiple blogs
• Ability to password protect a post, save as draft, or mark for later review
• Auto-recovery feature recovers posts interrupted by phone calls

Considering I am not getting an iPhone anytime soon I am thinking of installing the wordpress mobile plugin that can be used on a blackberry called Mobile Admin. I haven’t tried it yet but I am sure it is good for my needs of blogging on the run.
