I remember on my blackberry once I started pandora, to shut it down I had to hit menu and shut down pandora option. On my iPhone, I have only noticed a pause key and now way to "Shut Down" the app. Is this the way to do this? Also for my ipod part of the phone I hit pause as well, I just wanna make sure I dont start running my battery down with open apps. Also, is there a way to use songs on my iPod part of the phone as ringtones? Thanks
