I have the same problem! I'm buying that piece Dock Connector, but I see that has a battery to one side. and seeing the piece says that does not take the microphone included. I'm in doubt, because I only see a small battery in the connector Dock Connector.this is the part that you say? Charging Charger port flex ribbon for iphone 2G
ok, this error appeared to me and solved by removing the battery, then press the power button, without releasing put the battery until the hourglass appeared, let go and ready the system to recover, happened to me a model and one more!
