Ah, thank you. I would probably mess up more than I could fix.
If you have a geek friend nearby they could help you out. It is as simple as down loading a program or two and rebooting your phone. Just think of your computer when you first get it. It is full of bloat-ware (trial programs installed from the factory in an attempt to get you to buy them) that you have no interest in.
Rooting your phone allows you to remove that often unstable platform and get your phone to run better. If you have an HTC their "foot prints" and other programs would hog possessor time and battery.
