I was waiting for BlackBerry’s BBM team to finally add this feature to BBM for Android and iOS. The latest version of BBM adds the ability to find friends using BBM on Android and iOS by using your address book. This feature was in the leaked Gingerbread BBM leak for Android but this is not BBM v2.0 which is coming in a few weeks.
Check out the update sometime in the next 24 hours at the links below:
