No sound from 3GS earpiece during calls

Hey all,

I have an iPhone 3GS, and recently the internal earpiece stopped working during incoming and outgoing calls. I have to turn on speaker anytime I want to hear someone during a phone call.

I have replaced the earpiece: http://www.ebay.com/itm/251159616444...84.m1439.l2649

However, I'm still not getting any sound at all. The connector that attaches over it, the one with the cable marked "3" is somewhat bent. Should I try replacing that, and what exact part is that so I can order it?
