This is Part III in a series of iPhone reviews, tidbits, and thoughts.
Being the geek I am, I immediately bought a iPhone on launch day. By the time I got to the front of the line (three hours later) all AT&T had left were the 4GB models. So after my purchase I went ahead and bought a 8GB model via Apple.com.
When the model arrived I had my “oh crap” moment with the thought that I would have to manually transfer my data over to the new handset but to my surprise (and thrill) this process could not have been any easier. All I had to do was plug handset #2 into my PC, run it through iTunes, and wait about 30 seconds. All of my contacts and settings
effortlessly synced onto my new handset. Additionally, as expected, all of my iTunes content synced (music, photos, movies, etc.).
So fret not, if and when you upgrade to a different iPhone model or need to send yours in for service and are using a loaner, iTunes creates a backup of your phone every time it is plugged into iTunes.
