The Empower BlackBerry HTML Email Viewer Beta has been released to the public today. This viewer allows you to view HTML in your native BlackBerry Email Client. You can install it OTA from the following link on your BlackBerry. We will be running a review of the Beta later on today so stay tuned or subscribe to our RSS feed.
They plan on offering all of the other components of their BlackBerry Suite in modules so that you can install them piece by piece and only include the functionality that you need. Functionality that is coming soon is spell check as you type, rule based filtering, and folder support even if you have BIS. Empower is compatible with any RIM BlackBerry OS greater than 4.0.2 which is practically all the new BlackBerry devices that are in current circulation.
