I crossgraded from MissingSync Palm since I moved from Treo to iPhone. I'm pretty confused how they justify the cost of this product. For all it does I would say it should be free until Apple releases the Dev kit and this thing can actually do something useful. I accomplished my data migration without using this so now it's not much use at all. Even the notes sync is one way from phone to desktop. This is really the opposite of what you need. All I can say is if they manage to make it useful some day it had better be a free upgrade.
