Fun and games aside, the BlackBerry PlayBook acts as a device for professionals as well. We’ve seen some cool applications and games for fun so far, but haven’t seen much of what’s offered for professionals. The folks over at BlackBerryDownload spotted an application called Telnet Client, which is specific for PlayBook only. Telnet allows you to diagnose and debug TCP connections. The application is really straight forward just as you see in the screenshot above, and is offered free for the PlayBook as well.
