I finally get 2.1 on my Moment and now I'm lost and confused. 1. What the heck does root mean? Do I need to do it and how do I do it? 2. There is absolutely nothing showing up in the Market. What the heck? The only reason I updated was to get a certain app and now I can't pull up nothing. This sucks. 3. I'm totally missing it. What's the benefits of 2.1, b/c right now I can't come up with one thing.
