Go to the App Store and search for Facebook and Instagram then install it

Go to your App Store and search Facebook and then Instagram.
If you have your iTunes account, download both of them since they're both free.

Alternatively, you can use Safari and go to their mobile sites.

Go on the app store.
Find Facebook
Download it
Repeat for instagram
Hope this is clear.

Download the APP. First use your finger to press the power button on the top right of your iPhone, then when the bright box comes up, this is called the screen, slide the little arrow to unlock it, after that, some squares should come up, these are apps, go to the blue-ish one that says APP STORE on it, use your finger and TAP the app store, after you are in the app store, use the search bar on the top of the screen, and type in "Facebook" then click on it and install it, after that, go back to the APP STORE and type in "Instagram" in the same box, do the same thing you did for Facebook.
