This is a no-brainer. Since Apple doesn’t bring you any file-management goody to your iPhone and since you can’t just use the iPhone like you would use any other smartphone (notably, Android), it is virtually impossible to convert an iPhone into a flash drive.

Interestingly though, there are apps both on Cydia and the App Store that let you turn your iPhone into a flash drive for mass storage.

Before we dive into it, let’s understand what Apple lets you do with the smartphone:

  • You can use an app to store upload/store/edit files on the iPhone
  • You cannot access the file system without breaking into the phone (via jailbreak/SSH)
  • You cannot create “drives” per se without resorting to jailbreak apps
  • You can make use of the space as a pseudo-drive

iPhone as Flash Drive
We’re talking about using your iPhone as a flash drive to store data (and not create drives or partitions of your iPhone for which you’ll need to dig a little deeper with Cydia).

If you are looking to do this, precisely, we’ve got plenty of apps on the App Store that’ll get it done. For instance:

What you do is:

  • Install the app on your iPhone
  • Connect your iPhone to iTunes
  • Now, in iTunes, select your device from the top (or sidebar if you’ve got the sidebar pane visible)
  • Click on “Apps”
  • Click on “File Sharing” and then on “Flash Drive”
  • Now, you can click on ‘Add Files…’ to begin adding files that you want to go into the iPhone.

The two apps mentioned above are quite powerful. USB Flash Drive + in fact comes with support for a variety of files so you can open them right from within the app. To me, though, this is overkill because I just want to use the iPhone like a storage device.

    But I guess exporting it in to a computer where there is no iTunes will be a problem, will it not?

    i was able to copy files from a computer onto my iphone 6 plus using i-flash drive app. however, i was unsuccessful in exporting the files to a new computer… is this possible without jailbreaking?

      Use an ftp server app, there are a few free ones that have worked for me!
