Hi, I recently got an iPhone online, and it will ship pretty soon; I already have a brand new pair of these headphones: http://www.walmart.com/catalog/product.do?product_id=6023363 I was wondering if they will work on the iPhone. The one I ordered will NOT ship with headphones, so I was wondering if these will work? Looking at pictures provided, the little headphone plug looks almost exactly like the apple one? Thanks!!
