Hello, I have just received a new replacement for my iphone 4s. But when I get back home, I find out the the labels in the back cover of the phone are totally different from all the iphones that I've ever seen. It labels "Designed by apple in california". However the other labels are different. The other labels are not in English. It seems to be like japanese or chinese (show in picture). What's wrong with my phone? Has anybody experienced before? Please answer me.
