The Missing Sync for Symbian for Mac

From Mark/Space:

The Missing Sync for Symbian syncs your Nokia, Sony Ericsson and Motorola Symbian OS mobile phones with your Mac. Automatically synchronize personal contacts, calendars and tasks, plus your favorite music, photos, videos and files.

Sync contacts, calendars and tasks
Connect your phone with Mac OS X and synchronize contacts, calendars and tasks with iCal, Address Book and Microsoft Entourage.

Automatic synchronization
The Missing Sync for Symbian features Proximity Sync(tm) technology. This new approach to synchronization uses Bluetooth to sync data automatically when your Mac and phone are close to each other.

Sync music, videos, photos and files
The Missing Sync works with iPhoto and iTunes so you can take music, photos and videos with you wherever you go. The Missing Sync downloads iPhoto albums to your phone and resizes each image to fit the screen. Import video and pictures you take with your mobile phone's camera into iPhoto, easily. And, synchronize documents so they can be viewed and edited with handheld applications such as Quickoffice or Adobe Reader LE.
