The BlackBerry desktop manager has not seen an update in quite a while. With the rumors and partial confirmation from RIM that OS 6.1 is due this spring, it makes sense to see an upgrade to DM. The guys at BGR have posted some screen shot that confirm DM 6.1 will be out this spring also.
One of the things they notice is the it will be able to select not to use previous backed up or synced device data. Other than that there really isn’t much information available to us. We expect probably some changes in the appearance and more functionalities for 6.1 compatibility.
