I just got my iPhone 4. Still in the box. I can't decide whether to start it fresh or set it up from the last back up of my 3G. I am not worried about having to set up my email account, wifi, BT... etc i AM worried about importing potential problems from my old 3G which has been so laggy and not working right. Especially since I upgraded to iOS4. I want to add the apps back that I actually use. Has anybody gone this route? What should I expect first time I plug it into iTunes? Is this going to be a problem activating my new phone so it actually works and is able to make and receive calls? Thanks..
