WordPress App for iPhone and iPod Touch has been officially release [1]. At the moment, it is only available in the US iTunes Store, give it some time for it to propagate to the rest of the iTunes stores.
It is a free app and I recommend everyone who is using WordPress and has a iPhone or iPod Touch to get it.
Here is what it does (taken from Weblog Tools Collection [2]):
- Support for WP.com blogs and self-installed blogs version 2.5.1 and higher
- Embedded Safari for true previews of posts
- Full tag and category support
- Photo support for both camera pictures as well as library photos
- Support for multiple blogs
- Ability to password protect a post, save as a draft, or mark the post for later review
- Auto-recovery. This will recover posts which have been interrupted by phone calls
Check out WordPress for iPhone [3] or you can view/download the app in iTunes Store [4].
