It's sad but true; not everybody can have an iPhone. But for those poor souls with a supported Windows Mobile device, things just got a little bit better as Mark/Space has released version 4.0 of their Missing Sync for Windows Mobile with support for the new Windows Mobile 6 platform. New to version 4, Mark/Space has added plugins for video support (both ways), call logs, and SMS messages. And as always Missing Sync continues syncing support for iCal, Address Book, iTunes, iPhoto, etc.
Missing Sync for Windows Mobile is $39.95 and upgrade pricing is $24.95 from a variety of Missing Sync products.
