Free Backups of Your Contacts on Vz Wireless

I was logged on to Verizon Wireless recently and noticed that they have -- free -- if you use their online service called My Account, an address book backup system. You download a little application to your phone and you can use it to send your phone numbers. It is useful if my phone ever dies or I lose my phone, because I use my cell phone for nearly all of my numbers. The link for the backup service is here, although I was able to link to it from my My Account home page.
Update: What's especially neat about it is that you can do it automatically, so that in the middle of the night it will talk to Verizon Wireless and send your contacts without any intervention on your part.
As a side note, I never memorize people's phone numbers anymore. When I was in high school and college (and did not own a cell phone) I dialed nearly all of my friends' numbers, so through repetition, I memorized them. I even remember some of them to this day. But now that I have a cell phone, I just have to find the person I want to call in my contacts list and hit the send key, so I never remember the person's phone number.
As a second side note, over the summer (I think), Verizon Wireless started allowing you to see who you had spent money text messaging. That's useful if you wonder why your text messaging bill is so high.
