The Gmail app on my HTC Hero has stopped working............it won't do anything at all. I've tried going in and deleting the account (and setting it back up again), but it won't let you do that. The "Refresh" icon does nothing. And I've also tried going into "General Sync Settings" and it doesn't respond at all. It appears that the application doesn't communicate at all anymore with Google, and if someone can tell what the secret is, I would greatly appreciate it.
