just made on iTunes.
Note: When you make the backup, make two. Make a backup on iCloud. Then turn off the iCloud backup
option on your phone in the iCloud settings. Then when you connect your phone to your comp just make
sure you select the option of "back up to this computer" in the summary section. This way if you decide
to restore your backup, you have the option of doing it on iCloud or just on iTunes.
