COBBA is the name for audio IC in nokia phones, while CCONT is the power IC

To have a basic view of names and functions of IC's on any phone
U need to read a detailed schematic ( level 3 ) , print it and read it
all carefully.
Nokia explains in details every thing on the manual , if any body
still not understanding the all operation proscess , we can add a
thread to explain each component with its relashion ship with the
components in the phone.
