Where can I save PDF files on my iPad and be able to view them when I am not connected to Wifi? Both Adobe Reader and Books require me to be connected to wifi.
I attend a weekly Ukulele group where we play/sing from individual song sheets. The sheets are located online in my dropbox. The only option I can find at the moment is to print each one or take a screen shot and try to locate it in photos. There is no wifi available at the location.
