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:

Update

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...

If you still have the mentioned SMD coil and your iPhone starts up when connected with usb charger it's another problem. Start you own question!

The coil filters the USB data lines. Maybe your line is broken on another point?
