cooldude, if your BB coming to you is unlocked, that only means you can use it on another GSM network (such as ATT or TMo). It will still have its retailers branding on the face of the phone and the flash startup screen. You can't change that, and neither will an OS update.
However, you can update the OS, look at the sticky note at the top of the 8700 section for the latest and instructions.
