iPhone 3G and iPhone 3GS
This model introduced the iPhone’s naming pattern to the world. That is, the first model of a new generation is just a number, the second model has an “S” added. In this case, the “s” stood for speed; the 3GS offered a faster processor and faster cellular data, among other things.
The iPhone 3G’s core improvement was support for 3G wireless networks, something the original model lacked. The PDFs here provide legal info and some basic operating tips.
iPhone 4 and iPhone 4S
The iPhone 4S introduced Siri to the world. When this model debuted, it was the only way to get Apple’s personal assistant. The downloads here include quick tips for using the phone as well as basic legal info.
The iPhone 4 became famous—or, more rightly, infamous—for the “death grip” problem with its antenna. You probably won’t find mention of that in either of these downloads. That’s OK, just putting a case on your phone solves it.

iPhone 5, iPhone 5C and iPhone 5S
You’ll know the iPhone 5S as the first iPhone with the Touch ID fingerprint scanner. The available documentation for it is the same kind of basic legal information as for the 6 and 6S series models.
The iPhone 5C can be identified by the brightly colored plastic housing used on its back. It’s the same size as the iPhone 5—in fact, except for the housing, it’s almost the exact same phone. Like the 5S and 6 series, its download is just legal content.
The iPhone 5 was the first iPhone with a screen larger than the 3.5 inches the original models sported. This one has a 4-inch screen. At the same time the phone debuted, Apple introduced its new EarPods, replacing the old earbuds that came with the earlier iPhones. Documents here include a some quick tips for using the iPhone 5 and instructions for using the EarPods.
iPhone 6 and iPhone 6S
Like their larger siblings, the iPhone 6 and iPhone 6S are grouped together in a single document. And, again like those models, the information here is almost strictly legal and not designed to help you learn how to use the iPhone.
iPhone 6 Plus and iPhone 6S Plus
The iPhone 6 Plus and iPhone 6S Plus have their documentation combined into a single PDF, since the two models are very similar. You won’t find much in this document; it’s really for basic legal information. The user guides above are more instructional and for regular users
