How to open iPhone 3G / 3GS
by Q under Hardware tips & tricks

remove the two screws from the dock-connector end of the iPhone.
there is a rubber gasket between the silver front bezel and black display assembly. Some force is required to separate the iPhone’s display.
to remove the display use a small suction cup on lower end (near the Home button) and pull up the bottom section of the display.
the display is still connected to the PCB by 3 cables, so don’t try to remove it at this point. Rotate the display up until it is at an angle of approximately 90 degrees. Gently pull up the cables one by one.

In this way the users have full access to the printer bidirectional support which is the trigger of this error.
