jshoe22,
You can view them in your gmail account, it makes labels for your SMS, MMS, and Call log (Kind of like inbox, spam, trash labels). You can leave it with the default name it assigns which are the ones I mentioned, or you can relabel them. You can also use any gmail account, it doesn't have to be the one you use with your phone, but I like to keep everything together.
You should also know that it seperates them by sent and received (for each person). So for each person you have a conversation with is split into two. Unless I am missing a setting where you can put them together.
For me, I communicate with my work through both SMS and email so that's why I like the backup. I like it for the pictures in MMS because it does it instantly so I can just rummage through them later... plus I'm lazy so it works lol. Just my $.02
