Home button spring: necessary or not needed?
While replacing the LCD panel in my iPod Touch 2nd generation I desoldered the home button spring off from the logic board. Is this component a ground and needed for the ipod functionality or I don't bother with it and continue assembling the ipod ?

lemerise if you are referring to the little gold/copper "Z-Shaped" spring just above the dock connector in the center of the picture. That is what makes your home button work. It is the contact that, if it is broken or not attached, causes the home button to not work. Hope this helps, good luck.
@oldturkey: when I check the internal side of the digitizer assembly where the "gold/copper Z-Shaped" should make contact with the digitizer there's only a metal plate and no sign of the home button. Does it mean that when you press the home button this area of the digitizer will flex and enter in contact with the Z-Shaped metal thing and trigger the action or that the Z-Shaped metal thing is always in contact with the digitizer ? Just curious of how it works and I need to solder it adequately to get a good contact with the digitizer.
lemerise, I just checked on one of mine. When you turn your digitizer (with the home button attached) over you should see the home button contact and a brass part on the contact. That is the part that makes contact with the Z-shaped spring. With the digitizer attached, it should make contact at all times.

Home button spring can be purchased on Ebay for $9.99
Home Button Spring for iPod Touch 2nd/3rd Generation
That was the only place I found that sells it.
The diagram for the home button is like this: http://imageshack.us/photo/my-images/215... In that image when the digitizer is in place 1 and 2 are in contact with each other and 3 and 4 are in contact with each other. The button just completes the final connection.
If you don't want to pay $9.99 then you can just solder a thin wire between pad 3 and pad 4... that's really all the spring is doing (connecting 3 and 4). The home button when pressed will make the final contact.
