I have seen 5 iPhone 4 demo phones and 3 user phones and all have a flicker Has anyone else noticed a slight flicker when scrolling from the 2nd apps page back to the Home screen? It flickers and it's very distracting at times and I've a feeling it's not meant to happen. Didn't happen on my 3GS.
Here I another link about it as I thought this might be another big problem on the iPhone 4
I don't know man, but that's definitely why it flickers. Test it yourself. If you do it slow enough, there isn't a flicker. Also try going right a bit from the homescreen (start going to universal search) and you'll see what I mean.
It seems like there's a whole industry exists which single purpose is to try to uncover (or invent) and then trumpet every single possible niggle on 4G. Like tabloids constantly trying to dig out some dirt on their favorite celebrity couple. Guess price of popularity and backlash of sorts.
