Ok, so as title says I have an iphone 3gs which needed a dock replacement. Reason being my back button had failed due to the metal pads on the dock that make the connection to the home button had worn down. Anyway, I replaced the dock assembly and the home button worked, awesome I think, job done. Reassemble the thing and am very happy until I go to make a phone call, my girl friend informs me that she cannot hear a word I am saying as all she can hear is a static(ish) interference, it is very loud to her. I can hear it also however at a much quiter level. When i press mute (mic) or loudspeaker the noise dissapears.

At this point, please dont flame me for not searching the countless other threads with similar problems, I have done so, just to no avail. Many have said that it is due to the metal tab on the dock assembly that earths it is not correctly in contact with the chrome bezel. It is NOT this, in fact my original dock assembly with the broken home button has not got this earth tab anymore as it snapped off and when i have re-installed that assembly there is no interference. I have also ordered another dock assembly in case the first one i bought was faulty but this also doesnt work. I am lost, i have had my phone open and reassembled countless time, still no joy.

Has anyone else had the same issue, please help me out, this is doing my head in, all the hours I have put in just to get one damn button to work! Shame is such an important button!

Many thanks in advance to all who read this post and to those who reply, any ideas or suggestions are gereatly appreciated.

Tom.

hey men sorry for my english because I'm french ! you should try to disconnect the speaker cable (for this you need a "fer a souder" we say in french, i don't know the english word but i'm sure you see what i'm talking about) then you can remove the flex dock usb cable of the rest of the unit. Take your second flex cable and reassemble it with the first unit and I think it's gona be good. OR if you have a "fer a souder", what you can do is to just put down a bite of tin in the two parallele connector of the unit and it will make the contact ok, no need an other dock assembly or what else, just a bite of tin.

Ok, first of all, thank you. I think by "fer a souder" you mean soldering iron? I see what you mean about removing the speaker and then attaching the new flex to the original unit. I shall try this i think. I will let you know how I get on.

Problem solved, thank you. The first solution didnt work however then i just added tin to the two parallel points as you said in the second solution and it worked perfectly. Thanks again!

no problem men

do you know if there is something similar for the iphone 2g? I put in a new dock connector flex cable and I get that same horrible interference.

I've tried replacing the antenna cables, antenna flex, all to no avail.

Thanks for the help!
