The main problem I have is the US iPhone I have - I carry them both around and I can see the quality differences clear as night and day - if any of you are in Sussex I will happily meet you and show you what I mean.

although the people in London have seen them unless they have films and pictures on a new phone and another screen to compare it with they won't see the problem (as I said before)
So, effectively what you're saying is that you don't like the look of your UK iPhone screen and prefer the US one, while anyone viewing the UK screen on its own will think it is fine. Sorry, but I think as Tony says you really aren't going to get a UK panel you're happy with. Why not return the UK one, keep your US one and use it unlocked until v2 comes out or you spot models on sale that have screens you find satisfactory?
