I thought there was something odd about the display on my iPhone 3G, I previously had an iPod touch 1G and 2G, anyway I put my finger on it last night... When scrolling the screen is not smooth it's like it is interlaced or has too lower refresh rate, best place to see this is the settings menu, when scrolling the horizontal line between the items sort of goes light as you scroll the screen . It is very odd, and as I said my iPod touch did not do this and neither does my wife's iPhone 3G, I did a lot of searching last and could not find any mention of my issue via MacRumors, Apple Support or Google. Anyone else seen this or know a solution before I have to drive a 60 mile round trip back to the Apple store? Software updated to 2.2.1 on day of purchase + I have tried reset and restore, also I note my wife's iPhone is not perfectly smooth on the settings screen, but the divider line stays gray whereas mine looks like it flickers on and off as you scroll.
