The update is minor. Some people report problems with it. The OS you have now is good.

New to BlackBerry... you should join CrackBerry.

Spend some time here BB10 Leaked/Beta OS - BlackBerry Forums at CrackBerry.com

Several ways to load an OS - destructive (Autoloader), non-destructive (Sachesi). Depending on what you want, you then have to collect the right files. All that can be found in that link.
