I have the complete white conversion kit too, and looking at your photos, my kit is also from the same source, although I purchased my full kit from iphonefixed.co.uk in Wales.
The white headphone jack, and white dock connector, along with white front and back glass have been sat here for a few weeks now as I have read reports of some of these parts being ill fitting, so I have put off the conversion until i try the kit on a donor frame. I also have a water damaged iPhone 4 coming end of the month which I will try and fix, and will fit this kit to that most likely.
@Tom, you could send me your kit if you like, and I could document the conversion?
