The way I think the iPhone should sync is they way everything else syncs with the iPhone to a device. Then .mac (or other techniques) can sync multiple computers.

The way (for me) that the whole GTD approach works is by being able to get things instantly into a list for processing. My iPhone is always handy where I might not have my desktop or laptop immediatly accessible like in the car.

Using Jott helps but is not really a substitute for a tool for the iPhone. I have a context called iPhone as well.
