So, I had to reactivate my wife's old Palm Centro in the meantime. Not happy.
The only thing I have done recently is set up a rule for my work emails to forward to my gmail account. Maybe something happened when it was trying to refresh the received emails? I don't know.
I'd hate for this to have happened to anyone else, but if it has please let me know what might have caused it for you so we can make sure this doesn't happen again.
I'm gonna just let it keep looping until the battery wears out. Maybe that will fix it.
I'll have to spend a ton of time re-customizing the new one when it comes...hopefully it will be on time.
