Remember these parts ? Some websites were saying that it was iphone 5 's parts. Well they were wrong.

Would you look at that, Verizon's iPhone 4 has four notches punctuating its external antenna array -- one more than you may find on AT&T's version, with the top notch migrating to the side. Before you all jump on conspiracy theories about fixes and such, do bear in mind Verizon's variant uses a CDMA rather than GSM radio and this could be, and most probably is, just an innocuous aesthetic alteration.
