iPhone3GS component metallic fabric-like pad NEAR connector4?
Did anyone fix the old iPhone 3GS.
I know its old but mine was still functional until I tried to change the battery... and this pad split and part fell off. It is a metallic fabric-like silver pad beside connector 4. It is clearly visible as a rounded cornered rectangle about 1cm by 0.5cm, adjacent to connector numbered 4 in the ifixit teardown (pls see link below). It left a layer in place but shed a layer, looks metallic, what fell off conducts electricity, so I presume it is important to re-attach it for heat and/or electricity?
Please, does anyone know what it is for? And how to re-attach it? Or what harm if operate without it?
