I found a link to the latest version of the O/S (Package Version: 22.214.171.124) so I'm going to install that and see what happens.
Will the O/S upgrade blow away all my data?
Not a big deal because I sync with Outlook on my home PC. But I'm at the office and will be without my data till end of the day. No biggie.
Got to get your hands dirty during the learning process.
