Are you a Basecamp customer who also owns a BlackBerry? Unvired is looking for beta testers for a new app that brings Basecamp to your BlackBerry. If you'd like to help them test it out, send an email to support [at] unvired [dot] com along with the type of BlackBerry device you own.
Update: Unvired says, "We have received lot of requests and are not accepting any more requests for now." You can still email them to receive an announcement when the app launches though.
