WhatsApp recently updated their BlackBerry smartphone application from v2.7.4695 to v2.7.5032, which was released on March 13, 2012, from their website.
Let's hope they have fixed whatever issues the previous version had for this BlackBerry application.
Just a reminder that WhatsApp via BlackBerry App World has not been updated yet to the current version.
