I'm having a tough time finding a good skin for my white iPhone. None of the skins look good on a white iPhone. It looks like they were all meant for the black and not the white. Wooden skins like Trunket probably wouldn't appeal too well on a white iPhone.
I love my zagg clear shields, not good if you drop your phone a lot, it protects mostly from scratches, but will protect some from droppage. keep an eye out on zaggs twitter and they'll offer 50 percent off from time to time
May not be the type of skin you are looking for, but I am going to go with the Phantomskinz Matte skin for the back of my white iPhone (when I get it). I saw another thread on here and thought it looked like a nice combo.
