If a synchronization session is cancelled in iSync in Mac OS X 10.5, subsequent synchronization attempts may not complete, or may report an alert message.
This issue can occur if a synchronization session has been cancelled by clicking the "Cancel Now" button in iSync.
To begin synchronizing the Sony Ericsson W900i again with iSync, reset the phone device by powering it off and back on. Future synchronization attempts should work as expected.
