linda, it is possible that the "teeny tiny piece of white plastic" may have been essential. After all, the iPhone is full of those pieces. The #3 connector is for the earpice speaker and proximity sensor. You should try and check your display on a different phone, to determine if it is okay. Also, it would help if you could post an image from here. Make sure that your battery is indeed a battery for the 3g, double check all of your work. If you need the connector on the logic board repaired, contact " hectordtruong" on here. He does board level repair and has a great blog about the repair of connector #3. Search by his user name.
