I cannot tell exactly which iPhone this is. It does not have 7, or 9, or 11 printed on it. In tiny letters on the back it has: “Model A1661-?CG-E3087A IC 579C-E9087A” I am repairing it for a young grand daughter and she has no idea what it is. Thank you for your help. I will buy a screen as soon as I know which one to get.
Hello, According to the model number you supplied, it is an iPhone 7 plus. I highly recommend looking at this article if you are unsure. Apple provides a guide to see what type of iPhone you have. One good way to check is the phone body, if it has glass on its back, it could be an iPhone 8 or above. If the back is full aluminum, it could be an iPhone 7 or below. Another way to tell is the camera. Just looking at the camera is a ready sign of what iPhone it is. EDIT: I forgot to mention the color. The website I gave shows you the colors that are available for each model. That way, you can confirm the iPhone model. https://support.apple.com/en-us/HT201296
