The wizards of sync at Mark/Space have announced the availability of The Missing Sync for iPhone (for Windows). This is the Windows edition of the package that takes PIM data from your existing Palm OS, BlackBerry, Symbian OS, or Windows Mobile device and moves it to your sparkly new iPhone.
Like its Mac counterpart, the Windows version of The Missing Sync for iPhone comes with three separate applications that let you pull your SMS text messages, Call Log, and Notes from the iPhone. The app is available from Mark/Space for $39.95 and runs on PCs with Windows XP or Vista. To use the Migration Assistant feature of The Missing Sync for iPhone, you'll also need to have Microsoft Outlook 2003 or 2007 on your PC.
The Missing Sync for iPhone comes in English, French, and German localized versions.
In the interest of full disclosure, I wrote the User Guide for The Missing Sync for iPhone under contract to Mark/Space.
