WordPress Mobile Admin allows you to blog from your mobile.
WordPress Mobile Admin is a fully featured WordPress control panel for your mobile. It works on every device - no matter what it's capabilities, so it doesn't matter if you don't have an iPhone or BlackBerry, you can still manage and update your blog whilst you're on the go.
It uses Wapple's advanced web services to produce perfect markup whilst at the same time maintaining the familiar look and feel of WordPress. You can write and edit posts, moderate and reply to comments as well as updating and managing tags, categories and pages.
This plugin uses the same technology as the Wapple Architect Mobile Plugin and if you like this plugin, you'll love that one. Check out the home page here: Wapple Architect Mobile Plugin for WordPress
