seriously, we can what if till the end of time, but in reality, if the phone is that screwed up, i.e, you could not get it into restore or dfu mode yourself, then vodacom probably won't be able to either, that is, get it into any mode that allows them to access the phone, which probably means they won't be able to see the firmware on the phone anyways, ps, here, this particular what if might be a good reason to not replace the boot logos....
LOL, I know, that's why I was so scared last week, cuz the only thing that was showing on my iphone was the pwnapple logo
That's why when I jailbroke it yesterday I kept the apple logo...
