I am trying to get information on the ipad, ipod and/or the iphone. Which is the best one to get. I have a phone so I don't need another one, I wanted something to use the logos app on. Looking for something that doesn't cost much, but does a pretty good job. Maybe you know of someway to get a use one in a safe way. I know nothing of these things, but will like to learn and have this item in my pocket at all times. I know these things cost, but trying to get one that works, not the one with a lots of stiff on it, just one to run the logos app. Any advice!!!
