I've been playing around with it for awhile and can't find anything that's actually a significant upgrade except Do not Disturb. -Passbook doesn't work -Maps is missing half the data other maps apps have -Facebook intergration? Screws up all your contacts/ why would you want facebook having access to all your phones data. So is there anything else that was updated and I'm missing it? Or am I right in feeling that the "update" is a massive disappointment?
