Well you did not say that at the beginning. Not sure why you don't or can't use WiFi but to answer you question. Yes you can use it to update to Black. Just check that it is offering an update when you plug your phone in and not just a re-install of the current firmware. It displays a message telling you that there is a 'update' for your phone. Make sure that that the firmware that is displayed is different that that on your phone, which is also shown in the program.
Understand that this will completely wipe your phone of everything. I do mean everything.
