Android users have been swamped by a number of fakes in the Google Play Store. We're hearing that these fakes are actually the cause of the delay in launching the app for Google's open source OS. Still, the app should be available for Android users this weekend.
BBM will allow iOS and Android users to chat amongst themselves and BlackBerry users. It can tell you when a message you've sent has been received and read. At the same time, you will be able to tell when a recipient to one of your messages is working on a response. You will also be able to conduct group chats with up to 30 people participating at one time. And while video chat and screen share aren't in the original version of the app, a update down the road will add both features.
