I have a better deal for you!
You could ship me your device and I will back up all of your data for you. Of course I would need the password to your device but you have my personal guarantee that I will not prank call/text/email any of your contacts. Once I've created the backup, I will ship the device back to you. I can do all of this for the low, low price of $49.95. That's a $10 savings over Cellular Phonebook Backup & Transfer For Dummies!!!
And if you ever need your data backed up again, or even restored, just follow the simple instruction above!
