Il Mio Problema
The battery is dying...needed to replace it.
La Mia Riparazione
Opening the iPhone, I broke the very fragile home button cable (somehow!) I then ordered the home button cable assembly.
That did not go well, as I had to pry off the home button casing from the original phone & reuse it. There are no instructions written yet on how to do this.
Il Mio Consiglio
Buy the home button ASSEMBLY, not the home button cable!
