You can determine if an iPhone 4 has 8GB, 16GB or 32GB of storage by checking its capacity in the "Settings" menu. Unlike some previous versions of the iPhone, the iPhone 4 does not clearly label its storage capacity on the backside of the device. Checking the iPhone 4's capacity without referencing the serial number requires powering on the device, but iOS doesn't make any effort to conceal the device's used, available and total storage space.

Step 1

Turn on the iPhone and go to the Home screen.

Step 2

Tap the "Settings" icon.

Step 3

Select the "General" section from the third options cluster.

Step 4

Tap the "About" option found at the top of the "General" settings menu.

Step 5

Scroll down the list and look for the "Capacity" section.

Step 6

Check the number to the right of "Capacity." If the number is less than 8GB, the phone is a 8GB model. If the capacity is greater than 8GB and less than 16GB it is a 16GB model. If the capacity is larger than 16GB the iPhone 4 is a 32GB model.
