Mold/Mildew on inside back on iPhone 4?

[Hellion]

I tried taking a pic of what looks like mold or mildew on the inside back of my iPhone 4. I have babied this thing, no water or moisture to my knowledge one bit. But it does look gross looking at it from the back. Anyone else with this? I am going to be going into an Apple store this weekend, but I really don't wanna hear them say oh you got it wet or anything.

Weird. It looks almost like it is the paint/coating/whatever it is coming off the inside of the back glass. It will be interesting to see what they say and if this ends up affecting others eventually.

You can always try to check the water sensors ahead of time. There is one up inside teh dock connector area and one in the headphone jack.

It looks like what happens when moisture gets on a surface and then dries. Was there a chance that that could have happened?
