It’s a mobile app kind of week 🙂
The WordPress BlackBerry App is out of beta and ready with it’s 1.0 release.
Just like the other WordPress mobile apps it’s open source and free. You can find more help and info in the FAQ, forums, and Trac site (for tickets and patches).
These mobile apps use XML-RPC to communicate with your WordPress blog, so make sure you have that enabled first. You can find that in wp-admin under Settings -> Writing in the Remote Publishing section.
