A BlackBerry is a brand of smartphone that, depending on the model, offers features like video recording and wireless Internet. Research in Motion, the phone’s developer, created a uniform method of editing settings and accessing menus for all of their BlackBerry devices. For instance, all BlackBerry users can change the volume of the ringtone and the volume of their phone calls in the same way.
