Thinking ahead, and curious what others plan to do.. I upgraded my 3G 16gb to iOS4 (Gold Master candidate) about a week ago. That upgrade required a clean install, and I restored from my last backup. Unfortunately, even the core OS apps (iPod, Phone, Mail, etc.) run very slowly... Of course, this is essentially the final developer preview, not necessarily the final version released tomorrow, and no one has any great hopes of iOS4 working all that well on the 3G anyway.. That said, I can't help but think the core slowness is from some of the bloat inherent to all the current apps + the apps long deleted. Perhaps there are some of the SQL lite tables retained, etc. etc. I'm in the mind that I will not 'restore' when I get the iPhone 4 this week, but start with a clean slate.. Thoughts??
