No USB Connection after I broke little SMD element near connector #4!

I can neither charge the iPhone nor connect it to iTunes. Nothing happens when the phone is connected to a USB/charging cable. If the iPhone is off, connecting a cable turn it on.

It seems I broke a little SMD element near connector4 of the logic board when I disconnected this connector with a screwdriver!!!

Does anybody know what type of SMD element that is and where I can buy it? It is so little that I lost it on my table and never find that part again!

See picture:

I am having this problem, but I just checked my board and that SMD looks perfectly intact. What else could be? The connector 4 is firmly attached as well...
