iOS software quick-fire questions
What’s the best way to sync and read PDFs on iOS?
To read PDFs using the iBooks app, load them into the OS X version of iBooks and sync them using iTunes. For more ephemeral use, there are many apps which will read PDFs loaded
via iCloud, including the official reader from Adobe, GoodReader and PDF Expert. With iOS 9.3 and OS X 10.11.4, PDFs and ebooks can be synced to iBooks on all your devices via iCloud.
How can I back up my iPhone fully without iCloud?
The official alternative
is to connect your iPhone to a Mac or PC
over USB, then use iTunes’ backup feature. Third-party tools, such
as Syncios, only work with certain models, and their backups may not
be as complete.
