Sorry this is my first post but I really need some help. So I got was trying to replace the screen on my Iphone 2g and I ripped the signal cable. I ordered a new one from cnn.cn (http://cnn.cn/shop/apple-iphone-signal-cable-with-connector-p-2054.html) as well as a microphone and a loudspeaker. I know I am supposed to solder the microphone and loudspeaker on and I am fairly experienced with soldering but how do I solder them on. I can't quite figure out where the solder points are on the signal cable. I have no idea where to solder the mic onto. If anybody has any clue how to do this let me know because I feel like I'm grouping around in the dark. Thanks in advance and any help would be greatly appreciated. PS: Yes, I know how to solder.
