Seeing as ESPN Sportcenter happens to be one of my favorite free apps on my iPhone, I was pretty excited when I heard that ESPN was launching a Radio App today.  As much as my man Dan Patrick hates the mothership (ESPN), you have to hand it to their programmers for delivering some silky smooth apps.  Unfortunately for those always looking for a free app like myself, we will have to pony up a one-time fee of $2.99 to have access to all the popular ESPN Radio Shows like Mike & Mike in the morning, The Herd with Colin Cowherd, The Scott Van Pelt Show, The Michael Kay Show, The Michael Irvin Show and others.
