Are you positive? I thought it only remained unlocked after the last
couple of updates because the baseband radio wasn't being updated (like on
the 3G.) I assume the radio finally gets updated in 3.0 (just guessing- I
haven't looked seriously yet.) I've always "reunlocked" with each update
anyway just to be safe.
