At last, the much anticipated BBM 2.0 has landed and with it, voice calls for Android and iOS users.The headline act is that BBM Voice functionality, allowing you to make free calls to BBM contacts wherever they are in the world using a data or Wi-Fi connection. If you see the green icon, touch it and you make the call. Simple. Just make sure it doesn't wreck your data allowance.BBM Channels are also here, allowing you to chat with other BBM users about anything from hobbies and sports through to entertainment, fashion, cars and more. Great place to meet likeminded folk.Other new features include location sharing powered by Glympse, which can allow your location to be monitored for set time periods. Just so you don't feel 'tracked' all the time. There's also easier sharing of images voice notes and files with your contacts, Dropbox integration (to send a file from your personal cloud), new emoticons and larger BBM groups.So basically, well worth an upgrade or picking up for the first time. The new app is available for BlackBerry, Android and iPhone right now and is free to download.
