Beejive has announced a $5 discount off its popular BeejiveIM for BlackBerry app (regularly $19.95) in an effort to thank its “loyal BlackBerry community.” The sale starts tonight at midnight and lasts until midnight (PST) on Sunday, March 1.

They’re also lopping 5 bucks off the device-independent license, if you’re the type to carry around a backpack full of handsets:

In addition to the BeejiveIM for BlackBerry device license being available at a $5.00 discount, the user license will also be available for only $24.95, down from $29.95. The user license is for use on one BlackBerry device at a time but can be transferred to other BlackBerrys for free, allowing users to bring their license with them as they change models.

BeejiveIM for BlackBerry supports AIM®/iChat®/MobileMe®, MSN®/Windows Live®, Yahoo!®, MySpace, GoogleTalk®, SameTime®, ICQ®, and Jabber instant messaging services. We’re hearing that a notable update to the BlackBerry client is on the horizon, and that it won’t cost current owners a penny – so if you were considering buying your way in with the next release, might as well get it at a discount.
