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.
