Thank you very much!

Do you know what's for, and if I should reaplace it?

I can't hear or be heard only over cell calls, over IP works perfectly so Im wondering if this missed part is it cause.


That is easily possible, the missing connector is part of your POWER AMPS & RF FRONT END circuitry. I'd replace it and re-evaluate from there.


Thank's again oldturkey03!

What this part is for? What do?

Is for connect and test the amp?

Because I saw that is a just coaxial connector, and I can't find nothing in the phone that's suposed to be pugged there...

Thank you very much!!!
