After one complete month releasing the BBM app, the rollout for iOS and Android has finally started again. In order to avoid the circumstances as before which made the rollout to freeze, the company has now implemented a planned line-up system, to meet the high demands of Android and iOS users.
The reservation system is solely based upon user entering his/her mail after installing the app on his/her device. The email address would hold them in a spot in the queue and they will be notified when it’s their turn.
Also note that users who have already signed up in advance to use their messenger on the website of Blackberry would not need to be in the queue. So if haven’t registered before, you need to  be a bit patient.
Also users who are already using the app can enjoy the services as before. So do you have a say on the topic? Would you like to use BBM against any other messenger like Whatsapp? Leave your views in the comment section below.
