Do you want to "upgrade" your phone, as in get a newer model or do you want to "update" your phone, as in load a newer Operating System on it?
If you wish to update it, a good way of doing that is by using BlackBerry Desktop Software. If you don't have it installed on your PC, go to www.blackberry.com/desktop from your computer's browser. Once you have it installed, plug your phone in to your PC with a USB cord and open BlackBerry Desktop Software. Click Device at the top of the software then Update after that. If your carrier offers a newer OS version, it will show up in Desktop Software and you can load it to your phone.
I hope that helps you.
