When the BlackBerry PlayBook first released in April, AT&T did not support the BlackBerry Bridge app. This app was essential for connecting your BlackBerry smartphone to the PlayBook and allow the two devices to share data. Now, nearly 2 months later, AT&T has finally allowed the BlackBerry Bridge app to be downloaded by its customers. AT&T users must have a tethering plan included with their wireless service plan to take advantage of the Bridge Browser.
