Apple has released new versions of iCal and iSync.

Version 1.5.1 of iCal adds improved interface and time-zone support, enabling users to schedule and view events worldwide using any time zone. It also sports a new interface for creating and managing event details; a simplified Info Drawer to view and edit events and To Do details in one panel; unlimited customized calendar colours; keyboard shortcuts to hide and view calendars and create and edit events; and the ability to run AppleScripts triggered by iCal events.

iSync 1.2.1 adds calendar synchronization for Symbian-based smartphones. Apple claims iSync now supports “over 20” Bluetooth-enabled mobile phones from Nokia, Motorola, Sony Ericsson and Siemens. A full list of iSync-compatible devices is available at

Apple’s vice president of applications marketing Rob Schoeben said: "iCal and iSync give Mac OS X users access to their contacts and calendars wherever they go on their mobile phones, Palm OS PDAs and iPods. Used together with .Mac, Apple’s suite of Internet services, iCal and iSync allow users to effortlessly sync important information across multiple Macs.”

iCal 1.5.1 and iSync 1.2.1 are available immediately as free downloads. The updates require OS X 10.2.5 or higher, and publishing iCal calendars on the Internet requires .Mac membership.
