iTunes Won't Back Up iPhone 4

iTunes 10 (or 9) may not be backing up your iPhone 4. A lot of people have this problem but they don't notice it until they have to restore their iPhone and all their data is lost. To see if you have this problem, connect your device and iTunes, right click on it, and see if there is an option to back up your iPhone. If there is, your fine. If not, close iTunes, open terminal, copy and past: [defaults write com.apple.iTunes DeviceBackupsDisabled -bool false] (without the brackets) and hit enter. Open iTunes with your device connected, right click on it and you will now see an option to back up.
