How to replace audio jack port iPod first gen - M9724LL/A

Hello,

The audio jack in one of these is soldered to the motherboard. Which means that you would have to desolder and then solder a new one on. Parts for this can be found on eBay but if you don't know how to solder you would have to replace the whole motherboard which is quite hard. This will also remove everything you have on the device as you wouldn't have the same memory.

Here is a guide on how to remove and replace the motherboard and also a replacement part from ifixit:

Hope that helped
