Having trouble installing the latest Twitter for iPhone app?
If you're having trouble installing the latest Twitter for iPhone app, check to see how much space is available on your phone. Ideally, your device should have a minimum of 50MB of available space.

To see how much space is available on your device, follow these instructions:

Go to your device's Settings.
Tap General.
Under Usage, you can see how much memory is available on your device.
If your device has less than 50MB available, you may need to uninstall other apps to clear space.
Once you have more space available, try downloading the app again.

  • Why is my instagram connecting to the wrong twitter account? Hi, I had an old Twitter account connected to my Instagram that I deleted. I made a new Twitter account which is connected and logged into my iPhone, but every time I try to relink my Twitter to my Instagram, it automatically re-links to my old (deactivated) Twitter account.
