If you have less than 300k of memory available on your Symbian OS-based phone when you try to set it up in iSync 2 (included with Mac OS X 10.4 Tiger), you'll get the following error message:
Symbian OS-based phones (such as the Sony Ericsson P800 or P900, Nokia 3600, Nokia 3620, Nokia 3650, Nokia 3660, Nokia 6600, Nokia 7650, and Nokia N-Gage) need at least 300k of memory available for iSync 2 to set them up for syncing. A good way to make more memory available on your phone is to delete pictures, sounds, movies, or other applications that you don't want anymore (check the documentation that came with the phone for more information).
After making at least 300k of memory available, turn the phone off and back on again, then use iSync 2 to set it up for syncing.
If you're not sure what type of OS your phone uses, check the documentation that came with it to find out whether it's a Symbian OS device or not.
