Mentat BlackBerry Client Beta Available, Seeking User Feedback

We've been working on a native BlackBerry client for our free Mentat task management service and a beta version of it is now available for download.

We're looking for evaluations and feedback from users, particularly GTD advocates, so that we can make it even better.

For more information, please see http://brainmurmurs.com/blog/2007/11...-beta-preview/

New screens are up at our Mentat blog showing the new UI if you'd like to take a look.
Along with the click & drag functions in the Agenda view, we added color coded priority and notification icons to help get a handle on your tasks at a glance.
You can also set a sound alert to notify you when someone has sent you a task for better team GTD.
Feedback is welcome as always.

I tried to install it on my Blackberry Curve using the v42 OTA link, and it said the download failed with the message "907 Invalid COD Unable to import ZIP file".

I'd like to try it out--I don't see any other method to install it.
