Update: We received word from WhatsApp regarding the update.
The service model for WhatsApp on BlackBerry has not recently changed. Version 2.9.571 had bug which caused it to incorrectly display “lifetime service” in place of the correct service expiration date. This bug has since been fixed, and version 2.9.653 has been posted.
This bug only affects the display of the expiration date in the client, not the actual expiration date of the account.
The popular cross platform messenger WhatsApp recently updated to v2.9.571. This new update brings a nice change, after updating I noticed the app pricing change to Free Lifetime service.
The app also brings new emoticon, performance improvement and gives users on BlackBerry Free Lifetime service. To update to the new version click on settings, then about, check for update, or go to the following link. Now lets just hope they bring the app to BB10.
