Palm already lets you sync the Pre with iTunes via its clever pretending-to-be-an-iPod, but that only gets music, video and photos onto your phone. Missing Sync does the rest.
It's an extension of their other Missing Sync products that are already out for BlackBerry and Windows Mobile. It lets you grab contacts and calendar (great), as well as ringtones and podcasts, both of which were able to be synced before just with the USB disk mode. It costs $40, which is kinda high, but better than having to loop your contacts around into Google every time you want to do a sync. [Mark Space via Boy Genius]
