Server events and addresses sync to the phone,
but not from phone to server.

Discussions of this very common android issue, both on the web and with tech support, all lead to:
"Under Settings, open Accounts and Sync".
But this phone only has Accounts.
There are sync options for the Corporate Sync account--
but unsetting & resetting the check boxes does not solve the problem.
So I'm coming to think it's specifically a Photon issue.

Help would be greatly appreciates.
