With BlackBerry Blend having met an arguably early demise, folks looking to use BBM on their desktop have been out of luck with no desktop application available. That will soon be changing, though, as the latest BBM beta release for Android has introduced a new way to bring BBM to your desktop.
Keen eyes have noticed under the Me tab within the latest beta there's a spot that simply says BBM Desktop. When you tap on it, it opens your camera so that you can scan a barcode and gives you a URL to visit in order to obtain the barcode. Once scanned, you're logged right into a BBM session on your desktop where you have access to all your chats, groups and contacts.
For now, it all seems pretty barebones and you can only really chat back and forth. You can't upload images or files, and even BBM emojis are still missing for you to use but they show in chats and contact images don't really want to seem to sync fully but alas, it IS a beta so it's hard to be nitpicky about it. BBM Enterprise customers have a more robust desktop app available for download, so hopefully this web app for consumers will eventually reach a similar level. If you're on the beta, give it a go!
