Initially posted on Reddit this hack is genius for creating some extra space on your iPhone without deleting any of your actual content and apps. If you find yourself with less than 4GB remaining on your device (you can check this under Settings > General) then this trick is for you.
To gain those extra GB’s simple go to iTunes on your phone and pick out a really long movie to rent – The Lord of The Rings is always a good one! (Don’t worry you won’t actually be committing to purchasing or watching the cinematic film on your tiny iPhone!) Simply tap the ‘Rent’ button twice and when the notification appears saying that you cannot download the movie (because you don’t have enough room) instead of clicking OK hit Settings.
That’s it! Head back to About then General and marvel at the extra space you’ve just free’d up!
