I have an iPhone 3GS 32GB White that is five days old and i have noticed that around the speaker and microphone and around the sim tray there are very small cracks. At first i thought it was the plastic but after a closer inspection with the help of a magnifying glass i found that is the shiny coating that has developed the cracks.The cracks are very thin but under day light you can spot them. Does anyone else noticed this on their iPhone 3GS black or white?
