No 3g signal, what does this the rear wifi port control?
I have a customer whose buddy tried to open his 3GS iphone (A1303A) by prying it open at the silver antenna band around the phone. He succeeded in cracking the main logic board at the 3G antenna internally. I've replaced the dock port to find this only controls the wifi signal not the 3G signal.
In the 3GS teardown on step 12 there is a small, what looks to be a wifi port on the far right side of the back of the logic board.
Does anyone know if this is a connector for the 3G antenna? It appears that there may be a thin circuit line trailing to where the antenna "spring" pushes against the silver body antenna.
Has anyone tried to solder a direct line from this "port" to the case in order to get 3G signal again?
I was under the impression that label 7 was wifi antenna, not 3g antenna.
