A few months ago, Shep covered the goodness that is GoodReader for iOS. Just in time for the end of the year, we’ve got four copies of GoodReader for the iPhone to give away. The app normally costs $2.99, so this is the perfect little stocking stuffer for a tech-savvy friend or yourself. As the tweet says, simply @ reply us on Twitter with your favorite holiday hack by the end of Christmas day, and we’ll pick the four winners. Good luck!
