Skeptical!!!!!!!!!!!!!!!!!!!!!!!!!

Mein Problem

My iPhone wouldn't hold a charge very long, slow processing, but I like the small size of the 4S.

Meine Reparatur

I was a bit nervous seeing how my phone is my business and basically, my life is contained inside, but I googled iFixit 4S and followed a 11 min You Tube video and WHAMO!!!!!!!! Piece of cake!

Mein Rat

I do construction for a living with lots of fine dust and particulate matter. While you have the phone open use a Q-Tip and alcohol to clean inside your phone . Let alcohol evaporate before replacing the back!
