Congrats and welcome, for your 7130E, you need to set up via Enterprise Activation and then download the service books and then you'll see your browser icon.
If your uncertain as to how to do this, Sprint is just a phone call away and can walk you through it like they did for me which only took a few minutes.
I had the same problem..it was probably worst but I finally got it fixed. First you need a Blackberry data plan. Contact sprint by phone for this and then they will tell you the steps to get your phone activated over the network. They might have to re-provision your phone.
