I am getting a brand new 8330 from Sprint today. Upgrading from a Pearl. I think I'll go ahead and do a clean install of 4.5 before doing anything else (I don't use many apps except GMaps and JiveTalk) and see how that goes. Then I'll just sync my contacts from Outlook. Don't care about saving old messages of any kind.

Just installed DM4.5 and I have the 4.5 OS file downloaded, just waiting for the UPS guy!
