Thought people would want to know what I just heard from Sprint:

Of course I got up this morning like a kid wanting to watch cartoons....except that I wanted to get the new Biz Conn update. But no luck, it's not there yet as you've probably seen. So I talked to Sprint, and they said it won't be until late tonight(Saturday) -- maybe even after we've all gone to bed :-(
Seems to me like it would have been better to call it a "Sunday upgrade", but oh well.....Tick tock, tick tock....
