As you can perhaps imagine, it's difficult to make them out in the picture due to their hairline nature.
Are they definitely cracks, or just light scratches? If they are scratches, they should polish out, but if you do attempt you are at peril of removing any anti-glare coatings that may exist, as with the 8G.
If you're still in warranty, get the issue logged ASAP to cover you against any development, as I don't imagine replacements would be cheap!
