Hi all - my first post here and asking for your help... I had an iPod Touch bought for me for my birthday back in October last year and despite keeping it in a silicone back cover the back of the Touch has lots of tarnished spots on it. You can see photos that I have taken below: Please Register or Log in to view images Please Register or Log in to view images A friend of mine has some special Apple fluid cleaner called iKlear but that did not have any effect on these tarnishes. You can see the solution here... Does anyone know what has caused this? Has anyone had this problem with theirs and is this common? I am assuming this will be covered by Apple's warranty so should I contact them or go back to the retailer (Amazon.co.uk)? Thanks in advance for your help and advice on this.
