Without seeing your phone it is difficult to know what is broken or if it can be repaired, but here are some suggestions to get you started. The two socket style connectors and the FPC style connector for ribbon cables 1, 2,, and 3 (the cables connecting the front half of your phone to the back half) are all surface mounted on the logic board. If these are damaged it is very difficult to repair them and replacing the logic board is likely your only option. It takes a highly skilled technician to reflow the solder on these tiny components to replace them individually.

If the damage is in the ribbon cables or their "plug" connectors then you will need to replace the part connected to that particular cable. Repairing the cable material or the "plugs" on their ends is extra special difficult. Cable 1 is attached to the LCD display which can be replaced by itself. Cables 2 and 3 are connected to the digitizer (the touch sensitive front glass) and to the proximity sensor/ear speaker assembly respectively. These can be replaced as one unit with a front panel assembly, or the digitizer can be replaced alone with a front panel (but this is a bit more difficult procedure).

If the damage is clearly visible you should be able to determine which of these parts needs to be replaced. If you have not already, do take a look at the iFixit guide for the iPhone 3G for more details on replacing these parts. Good luck.
