If my iPad is too old to upgrade to the latest iOS, how can I use old apps?
I think I have upgrading the system software on my original iPad as much as I can, but some of my apps are now grayed out. I can no longer get to iBooks, Kindle books, or Nook books that I have purchased and saved.
What can I do to get to the older versions of those apps?
Thanks!
iPad, iOS 5.1.1
