So far:
I lost all of my email accounts;
tried to set them up again, but when I used the same name for the account, I got stopped by an alert that said that name was already being used by another account;
I picked a new name for the account and completed the setup, after I hit finish, it jumped to the Outlook account that had previously existed and the new account was not listed under mail accounts;
tried this a couple of times;
Did a hard reset, erasing all of my data, which isn’t a big deal I have had to do hard resets so often lately there isn’t much there;
After the reboot, I set up the accounts successfully, the device randomly powers off;
It is now frozen with a solid green colored screen, which I can do nothing about, it won’t even turn off, I am on hold now with my provider’s tech support.

This is my experience so far with the Windows Mobile 6.1 upgrade and the SMTP patch
