I would like to update my iPhone 5 to 7.1 (currently has the latest update before this one). Not able to connect to iTunes for now but am on WiFi. How much free space so I need? I have 3GB free. Do I need to wait until I can connect to iTunes. Always have done it over the air previously.
Tried Googling for this info but have not found the exact answer.
Thanks
