I’m writing this post on my iPhone using the just released WordPress application. Seamless install, and access to all my categories. Allows you to insert a photo from your iPhone library or take one with its camera. You can preview your work and when ready set a publish date and time.
If you are browsing your existing posts and notice a typo or simply want to say it differently, you can do it in a snap from your WordPress iPhone application.
A bit slow, and obviously you don’t have all the features of WordPress or a full keyboard, but it will come in handy when you just have to post. It’s also free. If you’re a WordPress blogger, you gotta get it.
