No service! opened iphone 3g to replace screen and now i dont get any service!

the antenna terminals(2) are located at the bottom right corner of the casing when the pcb is taken out. only one pin connected to the antenna pops out from the black enclosure. try checking to see if you screwed that part in well properly.

the second terminal is the fragile copper piece thats actually just soldered on the top of the pcb and can break when removing the pcb or replacing a screen.the copper is bent in a way to touch the aluminium/silver frame of the iphone. check to see that its still there . And if its broken replace it with thin copper wire soldered to the aluminium on the inside and the other point to the pcb.

goodluck

I just took mine apart for the exact same reason and now have the exact same issue. I'm going to take it apart again tomorrow and check the two terminals. I would like to know if you were able to get yours working.

I experience the same problem after I changed the housing, screen and battery.
WiFi, GPS works perfectly but GSM/3G coverage is major degraded.

I will take it apart again as well and verify the terminals you mentioned.

I will report if successful...

Have you got any pictures of the copper piece soldered on? just for something to guide me.

I guess you mean the small copper pin on the black piece and the other pin thing next to the "don not remove" sticker?
