When I got my new iPhone 4, I was very pleased, and everything worked perfectly. No trouble with the display or the design. Everything's perfect? No. A post on this forum about glitches between the glass and the metal/antenna frame made me take out the flashlight just to see if I had the issue. I didn't. However I discovered something greenish in the dock connection area of the phone. Looked like a couple of tiny "leaves" from a green vegetable. I used my sim card ejection tool to get rid of it. As I did so, the greenish substance was a bit gooey like, but not too difficult to get out of there. When this unknown substance was out in "the open" it had no colour, it was more clear or greyish. Anyone experienced this? Unfortunately I did not take pics of it, nor touch it with my fingers to get a feel of the substance. I surely hope it was nothing toxic from the factory.
