dock connector got wet - external speaker would not work - but blue tooth worked if USB cable was plugged in.
WHY did I fix it - because Apple annoyed me. Telling me I needed a new phone when I could reason out the problem was only the dock connector
The repair went great (that was fun)
The liberation tool (5 point head) only worked for 1 screw so I made a driver out of a eye glasses screw driver ( an idea from someone at Ifixit)
I used Duct tape to keep the screws safe and in the location they came from
the guide cover everything.
but the duct tape was my best idea
