BlackBerry BBM finally hits iOS, Android

 The app is set to go live in the next hour, according to BlackBerry's blog. BBM fans who signed up on the official site will be able to use the application immediately. But those who haven't can download the app to "hold your spot in line," and will get an e-mail when they can start using the service.  (The app is available now on Google Play and Apple's App Store.)  BlackBerry said 6 million people signed up for information on BBM.com.  "If you didn't sign up in advance, don't worry -- we are focused on moving millions of customers through the line as fast as possible.  Still, the delayed service for many casual users interested in BBM may turn off some users who had abandoned BlackBerry to go to Apple or Android, but were interested in reconnecting with BBM friends.

 NOTE: Samsung customers in Sub-Sahara Africa can download BBM today from the Samsung Apps store. iPhone and other Android users in Africa will be able to download the app in three days' time.
