Hi All, Replaced my 32 GB 3G with a 32 GB 4G. Before I upgraded I noticed the volume out of my 3G was definitely lower with IOS 4.0, 4.01, and 4.02 than 3.12. It was definitely lower on 4.0x IOS software. Now comes my shiney 4G with IOS 4.1 and I immediately notice the volume out is back to the #g 3.12 levels. My tired old ears are happy again! Anyone else wish to comment?
