Good luck and keep us posted!
I am also experiencing this problem... my smart cover magnet left a burn like stain on my ipad 2 and it seems to be recurring every time I put the smart cover on...
kindly update us on your endeavor...
hmm i get this to but i just figured it was dirt, but i use mine in a work truck
but it is a magnet and will pick up iron or steel dust and that would make gray marks
I wiped the side of my ipad 2 with a wet tissue (baby wipe) and it manages to clean the burn mark on my ipad, however, the mark is still there on the smart cover....
I wonder how did this happen? Is there any house wiring related to this burn mark? should I contact apple for clarification?
I noticed the same thing on my green smart cover. I got the stain off the iPad, but not from the smart cover. This is somewhat disturbing.
I had this on my first iPad and smart cover (I have been through 3 iPads and smart covers - long story).
Basically, the anodised or painted coating on the smart cover hinge was rubbing off, and so it was basically metal from the smart cover, rubbing against the metal of the iPad. On mine, it was on the hinge area of the smart cover at the top. I took it into the store, and had the smart cover replaced. Problem solved.
If I had left it and let it continue, it would have eventually started scratching the iPad.
Just noticed that mine has the same burn mark. I didn't spend over $800 to have the cover and iPad do this. The iPad has a wear mark and the cover has a burn through hole on the magnet strip. I will be stopping in to see the apple reps as soon as I can.
Finally I have found out what has caused my smart cover to bleed.. Its actually because I've charged my ipad with the smart cover on. And it is not just when i'm at home, I charged it at the office and also experiencing this burn mark... I'm definitely taking this smart cover back for a replacement...
