    I've tried to search, but the posts I see all seem to be aimed at jailbreakers. My iPhone 3G isn't jailbroken, and I'm not planning on doing so.

    But, the 3G has become quite sluggish since I update it to iOS4, and I would like to return it to the last version. Can some kind soul point me to the right place to learn how to do this? I have only upgraded to new versions in the past, never tried to go back.

    I'm not sure Apple did me a favor by allowing iOS4 on the 3G.

    I'd like some advice on this too, also for an unjailbroken 3G :)

    Yep, I have noticed this as well on my 3G and would like to retro-grade back to 3.1.3. iOS4 really has no benefit on 3G and I think it might be the new screen animations that causing this.

    Crickets? I guess we are alone in wanting to do this. Or maybe the only reason those who do know how to do it are jailbreakers who aren't looking here.

    Life goes on. I can deal.
