WordPress for iOS version 2.6 is now available in the Apple App Store. This updated version introduces several features for the iPhone, iPod touch, and iPad. You can now capture and post video right from your iPhone 3GS or iPhone 4, direct to your wordpress blog. The update also includes better support for Local Drafts, to prevent posts from disappearing, and autosaves your posts as you create them, just like the Web version does.
WordPress says that the update also includes other bug fixes and enhancements. The app is free and requires iOS 3.0.2 or later.
