Not quite. You have to have an unbranded device. As in its internal branding (T-Mo, AT&T, etc) has been removed from its memory. That way the phone doesn't know which carrier to poll for updates, so it polls MS. As far as I know this was only possible with a few Samsung phones. Otherwise you're stuck waiting on the manufacturer and carrier to release updates, even if your phone is unlocked.
