Long gone are the days of BlackBerries being the exclusive domain of the serious-minded, three-piece suit set. In the area I live, T-Mobile is known for being the "younger, hipper" carrier, and just look at their BB selection!
My most used applications on my BB are my MySpace, Facebook and IM clients- all used for personal use. Of course, all that having been said, I couldn't do my job without my BB.
Long live fun!
