During our continued testing of two iPhone 3Gs, we discovered last night that one of our units has a troubled headphone port; unlike our original iPhone and another iPhone 3G, unplugging the included Stereo Headset from the port mid-telephone call results 50% or more of the time in a disconnected call. Since many of you have units already, we’d like to ask in advance of our review: is this happening to your iPhone 3G? Please post in the comments…
