Feel as though with every email you send out from your device, that’s another brain cell you’ll never see again? Restore the stagnant cells with a solid read from BlackBerryInsight.com. Those kind, kind folks are offering up a free download of “The Art of War”, a great and classic read by Sun Tzu (who may have also written the Curious George series, I’m not sure). Head on over to their site to pick it up. Do it fast, though – it’s only available for the next 24 hours.
