Battery replacement on iPhone 3

Mi Problema

Phone kept turning off irradically. Used guide on ifixit to disassemble phone and found swollen battery.

Mi Solución

Went as advertised. I am very happy with the results. BTW the swollen battery yielded an added symptom of a dark spot in the center of the screen. That is now fixed as well.

Mi Consejo

Connector 3 is a little awkward to insert in socket, used a small set of tweezers.
