BBM now lets you set a Snapchat-style time limit for messages

BlackBerry isn't shy about borrowing features to keep BBM relevant in the messaging world; it added stickers to challenge WhatsApp, and now it's taking a page from Snapchat's book. The latest version of BBM introduces a timed messaging feature that lets you determine when messages and photos expire, so you don't have to worry that spies (or just nosy friends) will see what you said. To top it off, you can also retract messages outright -- you won't have to worry about accidentally sexting your boss so long as you delete the evidence in time. The privacy-minded upgrade probably won't get you to switch to BBM by itself, but it may be worth a look if you've wanted a slightly more sophisticated take on disappearing chat services.
