I recently upgraded to a pearl 8130 with Verizon.
I successfully installed the desktop manager software and I am able to synch my contacts, tasks and notes.
However as I watch the synch progress, it simply skips over calendar and doesn't synch at all.
I confimed that settings are correct in synch set up and this portion is set up exactly as is contacts, notes and tasks.
There are no error messages in the log either....
