There are two rings. Both must be connected on top of the bezel holder, not under! Otherwise you have no good connection to the bezel. The bezel works like a antenna Holder on bezel |

Member: 1147787 Status: Offline Thanks Meter: 12 | Hello ,the bezel is fine ,because when i put other iphone mainboard the signal is verry good.I think that this item is fault because when i pushed him stronger the signal has became litle bit stronger .But still no edge and signal strenght is almoust always at 2 .What if i push that component with hot iron ,maby he will stick better with mainboard ? If not i have bad mainboard is it posible to switch it ? Last edited by tomuxzz; 12-14-2010 at 15:04. |

Member: 1442842 Status: Offline Thanks Meter: 103 | Ok.. this little Part is a coil. This all is HF technik. Not easy to understand.. I had some phones too, with this effect. I try'd to change this coil, but it changed nothing. Sometimes i lost this part when i solder this out, he flips away, and never found.. :-) So i make a bridge with solder tin, and voila, i have a strong signal. You can try this, but carefully, when this not works, you can place this coil back. |

Now it's solved just by making a short between the antenna and the PCB... And let me tell you... iPad baseband (6.15) works perfect.... Greetings Community | |

Member: 1487836 Status: Offline Thanks Meter: 1 | Hi there I have the same problem is there any better pictures of the bezel / and the connector please, where on phone are they situated? (really excited as this seems to be the answer i've been looking for) but need to now if these fixes have worked and what exactly im looking for. Do I need to use special wire to bridge the gap? Please help, I feel like I've been trapped in the X-Files for the iphone (the truth is out there) ....somewhere. Thanks Rich |

Member: 1431277 Status: Offline Thanks Meter: 1 | Hi...I was an idiot when I opened my iphone 3G for the first time , and cracked the corner of the pcb where the antenna connector is. So now I have a very weak signal as well. Sounds like the same problem that DJ-JaaM had? Could someone (maybe JaaM?) tell me how to short this connection? Thanks! |
