These instructions will help you load/upgrade the OS on your device:
How do I upgrade the OS on my BlackBerry? - BlackBerryFAQ
Once you complete the upgrade, make sure your wireless is on (click on the wireless icon and then wait for the NXTL to appear in the top right corner).
To get the browser, click on the Options icon (wrench), then Adv. Options, then Host Routing Table (I think that's the correct path). When on the Host Routing Table screen, click the wheel and click 'Register Now'.
