I have very little experience with Apple products, but I may be getting someone's old first generation iPad in the near future. My only interest in it would be as a means of reading books I have purchased from Logos. My understanding is that the first gen iPad will not update past iOS 5.1.1. A quick Google search also shows that the current Logos app for iPad requires iOS 6.0. If I even do acquire said iPad: (1) will I even be able to install any version of the Logos app, (2) what extra hoops are involved in installing an older version (if it is even possible to do so), and (3) what kind of user experience can I expect? Thanks!
