I just left the retail store i bought my i phone 7 at, its rose gold , the rep showed me the white trim that wraps around the top and bottom of the phone, it is the external antenna he said. Its a new and improved feature to get better service etc... Very strong wave/ currant for better service!!! It's not even necessarily where you place your hand to hold the phone to touch it with the flesh but its so strong it was still affecting my hands and arms! Everyones body is different and you may or may not notice this problem of pins and needles or tingling yet, but it must be doing some damage that will be noticed by you body sooner or later in some aspect! Even got headaches! Beware of these features and do your research educate yourself and friends!

I just left the store I purchased my rose gold i phone from, clerk showed me a white strip at top and bottom of i phone 7 ,this is external antenna, I didn't even have to be touching it with my flesh , the current/waves coming from it were so strong causing pins and needles Tingling in my hands and arms, even getting head aches! Educate yourself and friends. These new improvements for better service reception are not good for your health! I didn't charge it in my room at night. i am switching phones, I can't take that feeling any more!
