Appendix B. Troubleshooting & Maintenance

The iPhone is a computer, and you know what that means: Things can go wrong. This particular computer, though, is not quite like a Mac or a PC. It runs a spin-off of the OS X operating system, but that doesn’t mean you can apply the same troubleshooting techniques.

One day you’ll connect the phone to your computer for charging or syncing, and—bam!—there’ll be a note from iTunes, or your Settings app, that new iPhone software is available.

So the first rule of trouble-free iPhoning is to accept these updates when they’re offered. With each new software blob, Apple removes another few dozen tiny glitches.
