I have a Treo 600 recently replaced by Sprint. Phone Info says it's hardware revision C, software "Treo600-1.20-SPR".

Alarms don't work. Scheduled things don't work. Nothing ever happens... Well, not quite. I loaded BackupMan, and scheduled times come and go without incident, but the next time I do something which modifies the appointment database, the pending backup gets run. Sometimes turning wireless mode on or off will cause the backup to run.

But... Apart from that, it doesn't work. Can't set alarms, can't do anything.

Anyone ever seen this before? I expect I get to go back to the Sprint store AGAIN, for about my fourth phone... ARGH!
