It seems that certain batches of 3G and 3GS had yellowy and 'warmer' displays than the rest which were nice 'cool' colour temperatures where whites actually look white. There are countless YouTube videos and experiences that show that the i4 is indeed 'warmer' in colour temperature than the 3GS. Much warmer. The issue is that a recent thread "entitled: White Balance Questions...w/ Photo Samples" has been strangely and recently deleted. The last few posts show two i4s one with a warmer yellow display and one that isn't yellow at all - like the mainstream 3GS models. This sets off alarm bells and I would like to know how many of you out there do not have a warmer colour display? Comparison with 3G and 3GS would be ideal.
