I have attempted use the phone for couple weeks now with no great improvement. I love the phone, but My Ears hurt/throb after using. Going home from work last night on highway I notice right away. It so bothersome have to hold phone away from ear to avoid issue. Its like driving down the road with one window open or putting your ear up to a sea shell. I can only determin thats its noice cancellation going on?? I tried using my Iphone 4 again and no pain in ears. I hate to return, but dont think software issue would fix it. Anyone else having this issue to the extreem of painful ear drum
