BlackBerry brings BBM Voice and Channels to Android and iOS, adds Dropbox sharing for good measure

BlackBerry has unveiled its latest version of BBM today, bringing the newer iOS and Android versions of the messaging and sharing app closer to feature parity with its BlackBerry 10 counterpart. Two main additions — BBM Voice and BBM Channels — are flanked by other seemingly minor, but together significant, features: location sharing using Glympse, Dropbox file sharing support for larger files stored in the cloud, and the expansion of the built-in suite of emoticons.
