Most users will find the transition into using an iPhone fairly smooth and will have very few problems with the
basic usability of their phone even without much research or practice. While this is definitely a good thing, many users tend to settle into a rut, using only the basic functions of the device and failing to capitalize on additional features. In many cases, this simply means less entertainment so it might not be a big concern. In others, however, it might mean less security and that should definitely be a concern. The iPhone has several security features enabled by default but users (particularly those new to iOS products) should at least be aware of a few additional safety features.
