The dock connector is brand new. It has NO dust or pocket link in it at all. I have replaced the dock assembly on an iPhone 4 before and have a clear mental picture of the before and after. Also,where the ribbon cable bends up and around the speaker assembly is an adhesive tab that has not been pulled off to expose the new adhesive.

No applications running, location services, or push notifications active. It does no appear in iTunes.
Now I need to know how to fix the overheating and charging problems :-(
