It took awhile for Automattic to bring a WordPress client to BlackBerry smartphones but that does not seem to be the case for BlackBerry 10. On the WordPress for BlackBerry Blog lead developer Danilo posted up some screenshots of his port of the Android client to BlackBerry 10 with custom styles for the device which works nicely. You can download it yourself here and sideload it. Danilo said he is also planning on working on a native Cascades version of the WordPress client after trying his hand with WebWorks.
Danilo has also updated the WordPress for BlackBerry smartphones app to v1.6.2. The change log simply states that the update brings reliability improvements across the board. Check it out here in App World.
