I'd like to download and read PDFs files offline on a 1st generation iPad that's been reset to factory settings.
I'm unable to install any apps - they always say that I need to update to the latest version of iOS, even if the app is compatible with iOS 5.1.1. I went to the App Store and they say it's because the apps from the AppStore are all 64-bit and my iPad is a 32-bit device. As a result, the seemingly simple task of downloading PDFs, saving them on my device and reading them later seems impossible.
How do I get PDF files onto my iPad for offline viewing?
Here are the screenshots of what apps I already have, and what happens if I try to install iBooks.
