iPhone 3GS Connector 7 Removal from Logic Board

I have looked all over the internet for answers on this and even asked a few people. So here goes, I need to remove the connector 7 bezel female piece from the iphone logic board. I need tips on how to desolder it without ripping the solder pads off, and what is the easiest method to reattaching the new one. I have heard of using a small mesh copper wire, i even saw where u could put a small copper wire on the female connection the solder the male part to it but that seemed to have failed for most people. The part is mangled on the logic board, i have a brand new dock assembly making sure the ground was soldered on the right side.. I just need a step my step tutorial or tips or any kind've help on how to remove the connector 7 radio/antenna female piece from the logic board. Someone has had to do this before. Thank you ahead of time for your time and your trouble. There are no youtube video's unless i just wasn't searching for the proper name of the piece. I have seem a few answers on this but they are all very vague and dont really have to do with removing the piece from the logic board.
