A friend e-mailed me a song in .m4a format. When I tapped the icon, it looked like the iPad downloaded it, but now I cannot find it in iTunes or anywhere else. Where did it go? Holding a finger on the icon does not bring up a Save Song option, nor an "Open With" option. Do I need an app of some sort? I'm an iPad newbie, so sorry if this is obvious. I did search the forum but could not find this specific answer.
