I've been using 4.0 on my 3G since the initial betas were released. I was hoping the GM version would address the performance issues, but no luck - I've had it installed on my phone since it was released around WWDC, so I don't think this is a Spotlight issue. Glad the iPhone 4 is coming tomorrow; the 3G really is almost unusable for me at this point (Google Maps especially).
