I got my new phone a few days ago and had it activated yesterday. On the first call I made there was an issue with some sort of feedback coming through when I ride down the road. It's hard to describe, but almost sounds like some sort of wind tunnel coming from the ear piece. It only happens when riding down the road (if I'm sitting on the couch for a call....it is fine), which leads me to wonder if it has something to do with the internals and the switching to and from LTE. Anybody else noticing anything similar? Trying to decide if it is worth the hour drive to the closest Apple Store. EDIT 9/29 It seems after some more digging at the noise cancelling features in the new phone are the culprit. Pretty bad, as it is a fairly severe effect at times from the phone. Anyone else experiencing this to the point where it is disorienting you or making you dizzy when taking calls on the new iPhone? My wife had me cancel her pre-order as a result and I'm seriously considering sending mine back.
