I've been posting on Hofo trying to find out exactly how GPS is blocked by VZW. Everyone has said everything from a provisioning lock to firmware, to the fact it's not real GPS, which it can't be due to the fact that every other 8x30 has real GPS.
It seems to me that it has to be something internal with the BlackBerry. I don't think VZW would take the time and money to fiddle with their servers to block GPS from being used fully on BlackBerries. It's cheaper and easier to do software/firmware than to lock it out by server.
If that is the case, which I can't figure out, then there has to be a way to be able to use GPS on a BlackBerry. I wish I could get my hands on a Sprint or Alltel BlackBerry with GPS and put it on my VZW account and see if that allows me to use GPS. I have VZNav on my account, so it should work right away.
Anyone willing to donate for a good cause?
