By now you may have noticed that updates are flying out like hot cakes from BlackBerry App World. I know I'm exaggerating, but it seems as if every app, at least the most popular ones, are getting updated with many great improvements. Slacker Radio for PlayBook was added to this list of recently updated, bringing the app up to v1.1.50. If you aren't sure what Slacker Radio is, it's a personalized music brought right to your PlayBook. This includes, unlimited free music, over 140 expertly programmed stations by genre, information regarding the song you're listening to and even allows you to listen to music while using other apps!
