iPhone 4 volume control not working properly
Why does my volume control buttons only work with my apple headset and mic installed. When headset not pluged in and I try to volume up or down I see the speaker logo with the word ringer above but no movement up or down. Also when in ipod mode the same thing happens. when headset pluged in volume works properly but with headset unpluged there in no volume control available. under settings-sounds-ringer and alerts-change with buttons-on. tryed power off and restart no help.
iPhone 4, iOS 4.3.3, iOS 4.3.5
