I have a problem with my book port. I probably will have to send it back, but, really hate to have to do that though. The earphone jack is loose, or there's a short, but, sometimes I have to move the book port or the earphone around because it cuts out. I am still using it, however, and wonder if when I send it back, will it mean a $60 repair, or more? Also, how long might it take to have it looked at?
