Yesterday, as I synced my 650, my entire calendar was gone! I tried and tried again but to no avail. I ended up doing a hard reset and I've got my calendar back.

Now the problem. Everything is working EXCEPT my TREO does not find or recognize my BT devices. It does find my computer but not any BT headsets.

I can push the buttons on the headsets and the TREO makes a noise like it's trying to connect and it tells me it is trying to connect but the connection fails.

Any suggestions?
