Depends on what you want to do with it. Setup your email account? Google Maps? Upload your music to it? Go thru your phonebook to make sure everything comes across right? Setup your various accounts..... Facebook, Ebay, Gmail, etc.
I think my Commando already got the upgrade a couple weeks ago. I don't have PTT enabled at this point. Mainly because all my buddies ride an Iphone, Bionic or whatever other phone.
Good luck & enjoy it.
