My new 3GS arrives today. I currently have a 3G with the 3.0 firmware on it. Should I set up the 3GS "fresh" or should I do a restore as part of the process (in other words, should I select "Set up as a new phone" or "Restore from backup of:")? For some reason, it seems cleaner to me to just "start over" and set up all of my settings and sync preferences from scratch. Thoughts?
