I have the Glacier Otterbox Defender with the white shell and grey rubber skin on my white iP5 now while waiting for the Lifeproof to be released. I have not had any issues with the white getting dirty; however, I work in healthcare so my phone isn't really "in the elements" and exposed to a lot of dirt during the day. I have a friend who has the white & black version with the black shell and white rubber skin (found @ AT&T) and the white rubber is a dirt magnet. It looks like he rubbed sunless tanning lotion all over it. It started looking really nasty after only a week of use, so I would advise everyone to stay away from that one.
