Updating an iPhone 3GS to iPhone 4.0

Apple makes the process of updating an existing iPhone very simple by using iTunes as the tool for all software updates, applications and backup of the settings, content and other information.

If you have an iPhone 3GS (there appear to be some issues with the first generation phone, iPhone 3G, so updating at this time is NOT recommended), a connection to your computer with the USB cable should start iTunes and let you know there is a software update for the iPhone. I would recommend a Download and Install choice and give the process at least 30 minutes.

iTunes first downloads the latest version of the iPhone software (iOS 4) and then will erase, update and ask if you want to restore all your information to the iPhone as it was before you began the update. For most users, this is what I would recommend since the system will put music, movies, settings for email and calendars as well as photos back onto the device. Again, this could take another 15-30 minutes depending on how much info you have or had on the phone, so it is recommended that you do not do this when in a rush or heading out of the house for some reason…

Since iTunes manages your media and your iPhone, it is recommended you connect the iPhone to a computer once every week or two. This accomplishes a few things. It backs up your phone, data and settings. It will pull photos and videos from your phone into iPhoto for sharing and checks with Apple to see if there are updates to your phone which could improve performance, stability or reliability.

Questions – let us know…
