Can you print out a help manual for the iPhone 4 online?

Digital versions of all Apple iPhone 4 manuals are available in PDF format to download and print out from the Apple Support website. The manuals are also available from third-party websites that specialize in cellphone information such as GSM Arena or PhoneArena.com.

Apple publishes two manuals for each iPhone version, including iPhone 4. A warranty, safety and regulatory manual includes legal information and disclosures about how to safely and legally operate the iPhone. A quick-start guide called "Finger Tips" includes information about how to navigate the Apple iOS operating system that runs on the iPhone, and how to start using the iPhone for those unfamiliar with the device.
